- Read the periodic table from top left to bottom right. The elements are ordered by their atomic numbers, which increase as you move across and down the periodic table.
- Observe that each element contains 1 more proton than its predecessor. You can tell this by looking at the atomic number.
- Recognize groups, which share physical and chemical properties. Groups, also known as families, fall in a vertical column.
- Notice why gaps exist in the table. Although elements are ordered based on their atomic number, they’re also arranged into groups and families that share the same physical and ...
- Notice that each row is called a period. All of the elements in a period have the same number of atomic orbitals, which is where their electrons go.
- Distinguish between metals, semi-metals, and non-metals. You can better understand the properties of an element by recognizing what type of element it is.
- Atomic Number: the number of protons in the nucleus (which is the same as the number of electrons in the atom).
- Name: the element's common name.
- Symbol: a one or two letter symbol that represents the element.
How do you find elements in the periodic table?
How do you find elements in the periodic table? To find the number of electrons an element has, locate it on the periodic table of elements, find the atomic number, and note the number of protons; because atoms are naturally electrically neutral, the protons and electrons are usually equal. Look at the oxidation number for further information.
How are the elements arranged in the periodic table?
Key points
- The modern periodic table arranges into a unique arrangement that can be used for reference.
- Metals are found on the left of the periodic table and non-metals on the right.
- The periodic table is arranged in rows called periods and columns called groups, which can be used to locate any element.
What is the Order of elements in 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. The atomic number of an element is the number of protons in the nucleus of an atom of that element.
How are element listed on the periodic table?
Three systems have been used to number families and groups:
- The older IUPAC system used Roman numerals together with letters to distinguish between the left (A) and right (B) side of the periodic table.
- The CAS system used letters to differentiate main group (A) and transition (B) elements.
- The modern IUPAC system uses Arabic numbers 1-18, simply numbering the columns of the periodic table from left to right.

What do the numbers on the periodic table mean?
Most periodic tables include a value for atomic mass (also called atomic weight) on each element tile. For a single atom of an element, this would be a whole number, adding the number of protons, neutrons, and electrons together for the atom.

What is an element in the periodic table?
Vocabulary. Elements: A pure substance composed of a single atom. Groups: The vertical column of the periodic table that signifies the number of valence electrons in an element.

How are elements organized in the periodic table?
The periodic table is organized into groups (vertical columns), periods (horizontal rows), and families (groups of elements that are similar). Elements in the same group have the same number of valence electrons. Meanwhile, elements in the same period have the same number of occupied electron shells. In 1869 Russian chemist Dmitri Mendeleev noticed there existed an innate pattern of organization for the chemical elements. From this deduction, he formed the periodic table. It is important to note how the location of elements on this table tells us about their properties. A quick way to understand an element’s chemical and physical properties is to know the periodic trends. These trends tell you where the highest and lowest types of properties are concentrated on the periodic table. For a more in-depth explanation of periodic trends, click here.
What is the name of the group of elements that are found in the three states of matter at standard temperature?
The name halogen means “salt formers” in greek. This is evident in nature as halogens interact with metals to form various salts. On another note, the halogens are a unique group of elements. They are the only periodic family that contains elements in the three states of matter at standard temperature. There are 6 halogens and they are located in group 17. These elements include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are highly reactive, highly electronegative, and highly toxic non-metals.
How many periods are there in the periodic table?
Periods are the horizontal rows of the periodic table. There are seven periods total and each element in a period has the same number of atomic orbitals. The top period, which contains hydrogen and helium, has only two orbitals. As you go down the rows, the number of orbitals increases.
What are the families of elements?
These families are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases. Many of these families belong to a single group. However, not all of the families overlap ...
Which scientist discovered that elements in the same period have the same number of electron shells?

How to Read a Periodic Table of Elements
A periodic table of elements places and groups the elements which existence we have identified based on their nature. You may notice some gaps that the periodic table of elements has in the middle. That is because we place the transition metals group there which nature is quite different from other elements.

Which element has the first atomic number?
Hydrogen (H) is the first element with an atomic number of 1. Beginning with hydrogen in the top left of the table, atomic numbers increase from left to right and top to bottom. However, this ordering is not indicative of the size of the elements. Ask Question.
Which element is the smallest in the atomic radius?
Atomic radius is ordered beginning in the top right of the table with helium (He) being the smallest element. Size increases on the table from right to left and top to bottom with the element in the bottom left of the table (francium of Fr) being the largest of all the elements. Ask Question.
CORE Concepts
- Read the periodic table from top left to bottom right. The elements are ordered by their atomic numbers, which increase as you move across and down the periodic table. The atomic number is how many protons the element’s atom possesses. You’ll also notice that each element’s atomic mass increases as you move across the table. This means you can recognize a lot ab…
