How many elements are in the periodic table?
The table below consists of 118 elements of the periodic table, sorted by atomic number, atomic weight, symbols, density, discovered year and the group.
What is the atomic number of an element?
The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of [He] 2s 2 2p 2, since its atomic number is 6.
What is the number of protons in the nucleus called?
The number of protons in the nucleus is called the atomic number. The atomic number of each element is unique.
Why is the atomic number of each element unique?
While the atomic number always stays the same some elements have atoms with different atomic mass numbers. This is because some elements have a different number of neutrons in the nucleus.
How to find the mass of an element?
The number of protons and the number of neutrons shall determine the mass number of an element. Since the isotopes of an element have slightly different mass numbers, it calculates the atomic mass by obtaining the mean of the mass numbers for its isotopes.
How can periodic trends be observed?
Periodic trends in the properties of the elements can be observed down the groups and across the periods of the modern periodic table. Every chemical element has a specific atomic number, which provides insight into the number of protons present within its nucleus.
Why is the atomic number important?
This number is very important, because it is unique to a given element’s atoms. An element’s atoms all have the same number of protons and each element has a different number of protons in its atoms. Test your knowledge on periodic table elements.

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.
Where does antimony come from?
Antimony. Latin antimonium, the origin of which is uncertain: folk etymologies suggest it is derived from Greek antí ('against') + mónos ('alone'), or Old French anti- moine, 'Monk's bane', but it could plausibly be from or related to Arabic ʾiṯmid, 'antimony', reformatted as a Latin word.
What are the abbreviations for elements?
In fact, there are eleven of the abbreviations for the elements which don't seem to match the modern name. Those are subtle reminders of the history of the Periodic Table and the process of the discovery of elements over the millennia. Eight of these oddities are Au (gold), Ag (silver), Cu (copper), FE (iron), SN (tin), Pb (lead), Sb (antimony), and Hg (mercury): All were among the elements recognized by the ancient Greeks and Romans, and the abbreviations for those are based on a Latin or Greek term for the element.
Why do we use symbols in the periodic table?
It's easier to navigate the periodic table and write chemical equations and formulae once you know the symbols for the elements. However, sometimes it's easy to confuse symbols of elements with similar names. Other elements have symbols that don't seem to relate to their names at all! For these elements, the symbol usually refers to an older element name that isn't used anymore.
What does the word "K" mean in the word "potassium"?
Potassium was identified during the Middle Ages, and it's "K" is for kalium, a medieval Latin term for potash. W stands for tungsten because it was first identified in 1780 within the mineral known as wolframite, by French scientist Antoine Lavoisier (1743–1794).
How many elements are there in the periodic table?
Mendeleev left spaces for elements he expected to be discovered, and today’s periodic table contains 118 elements, starting with hydrogen and ending with oganesson, a chemical element first synthesized in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, by a team of Russian and American scientists.

Which element has endured in Mendeelev's periodic table?
They had even been organized by similar properties before. So why is Mendeelev's periodic table the one that has endured? Lou Serico explains via eka-aluminum, an element whose existence Mendeelev predicted years before it was discovered.
What element makes high tech work?
One of my favorite elements is Dysprosium because it takes part in making many of our high tech systems work due to extra strong high temperature magnets that it facilitates.
What is periodic chemistry?
The term “periodic” is based on the discovery that elements show patterns in their chemical properties at certain regular intervals. Were it not for the simplification provided by this chart, students of chemistry would need to learn the properties of all 118 known elements.
What metal has the highest melting temperature?
Tungsten! It’s the metal with the highest melting temperature (over 3400ºC!) and extremely strong. It’s used in fusion as a plasma-facing material because of its ability to withstand extreme environments.
Who created the periodic table?
Attempts to classify elements and group them in ways that explained their behavior date back to the 1700s, but the first actual periodic table is generally credited to Dmitri Ivanovich Mendeleev, a Russian chemist who in 1869 arranged 63 known elements according to their increasing atomic weight.
