What is a chemical element?
A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, or Z). Therefore, the elements can be listed by the number of protons in the atom of each element as listed below.
What information can I find on the periodic table?
Each chemical element contains a link to a page that explains its chemical properties, health effects, environmental effects, application data, an image and also information of the history/inventor of each element. Click here for the history of the periodic table.
What is the chemical name of hydrogen?
Hydrogen is the element with atomic number 1; helium, atomic number 2; lithium, atomic number 3; and so on. Each of these names can be further abbreviated by a one- or two-letter chemical symbol; those for hydrogen, helium, and lithium are respectively H, He, and Li. [6]
What are the elements in the Group 1 of the periodic table?
a Group 1 is composed of hydrogen (H) and the alkali metals. Elements of the group have one s-electron in the outer electron shell. Hydrogen is not considered to be an alkali metal as it is not a metal, though it is more analogous to them than any other group. This makes the group somewhat exceptional.

Why is the chart called periodic table?
Why is the periodic table called the periodic table? It is called the periodic table because of the way the elements are arranged. You'll notice they're in rows and columns. The horizontal rows (which go from left to right) are called 'periods' and the vertical columns (going from up to down) are called 'groups'.
What is the periodic table used for?
Scientists can use the table to analyze reactivity among elements, predict chemical reactions, understand trends in periodic properties among different elements and speculate on the properties of those yet to be discovered. The modern periodic table arranges the elements by their atomic numbers and periodic properties.

What is called a chart?
A chart is a graphical representation for data visualization, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart". A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info.
What is periodic table in simple words?
What is the periodic table? The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson.
Can a chart be called a table?
Visual elements are referred to as either Tables or Figures. Tables are made up of rows and columns and the cells usually have numbers in them (but may also have words or images). Figures refer to any visual elements—graphs, charts, diagrams, photos, etc. —that are not Tables.
How do you read periodic table?
When you're reading the periodic table, move across the table from top left to bottom right. As you move across the table, the number of protons and the atomic mass of each element increases. Each element has its own atomic number, which represents the number of protons in one atom of the element.
What are 118 elements called?
Nihonium, moscovium, tennessine, and oganesson are the permanent names for elements 113, 115, 117, and 118, the International Union of Pure & Applied Chemistry (IUPAC) announced today. The permanent names for elements 113, 115, 117, and 118 are nihonium, moscovium, tennessine, and oganesson.

What is the name of the atoms that have the same number of protons?
A chemical element, often simply called an element, is a species of atoms which all have the same number of protons in their atomic nuclei (i.e., the same atomic number, or Z ).
What is the melting point of helium?
List. ^ Helium melting point: helium does not solidify at a pressure of 1 bar (0.99 atm). Helium can only solidify at pressures above 25 atmosphere, which corresponds to a melting point of absolute zero (0 K). ^ Arsenic: element sublimes at one atmosphere of pressure.
What is the periodic table?
The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on ...
What are the columns of periodic table called?
The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups , contain elements with similar chemical behaviours.
What is the atomic number plotted against?
Atomic number plotted against atomic radius, excluding the noble gases. Atomic radii vary in a predictable and explainable manner across the periodic table. For instance, the radii generally decrease along each period of the table, from the alkali metals to the noble gases; and increase down each group.
What are metals and nonmetals?
In chronological order, this section discusses metals and nonmetals (and metalloids); categories of elements; groups and periods; and periodic table blocks. While the recognition of metals as solid, fusible and generally malleable substances dates from antiquity, Antoine Lavoisier may have the first to formally distinguish between metals and nonmetals ('non-métalliques') in 1789 with the publication of his 'revolutionary' Elementary Treatise on Chemistry. In 1811, Berzelius referred to nonmetallic elements as metalloids, in reference to their ability to form oxyanions. In 1825, in a revised German edition of his Textbook of Chemistry, he subdivided the metalloids into three classes. These were: constantly gaseous 'gazolyta' (hydrogen, nitrogen, oxygen); real metalloids (sulfur, phosphorus, carbon, boron, silicon); and salt-forming 'halogenia' (fluorine, chlorine, bromine, iodine). Only recently, since the mid-20th century, has the term metalloid been widely used to refer to elements with intermediate or borderline properties between metals and nonmetals. Mendeleev published his periodic table in 1869, along with references to groups of families of elements, and rows or periods of his periodic table. At the same time, Hinrichs wrote that simple lines could be drawn on a periodic table in order to delimit properties of interest, such as elements having metallic lustre (in contrast to those not having such lustre). Charles Janet, in 1928, appears to have been the first to refer to the periodic table's blocks.
How many categories are there in the periodic table?
The elements of the periodic table shown here are divided into nine categories; six for the metals, and two for nonmetals, and a metalloid category. The nine categories (or sets) correspond to those found in the literature for the applicable part of the periodic table. Different authors may use different categorisation schema depending on the properties of interest.
When is the 150th anniversary of the periodic table?
In celebration of the periodic table's 150th anniversary, the United Nations declared the year 2019 as the International Year of the Periodic Table, celebrating "one of the most significant achievements in science".
When was the periodic table first published?
Periodic table at the Chemical Auditorium of the Gdańsk University of Technology, 1904. The first version of Mendeleev's periodic table, 1 March 1869 (N.S.): An attempt at a system of elements based on their atomic weights and chemical similarities.
