Argon Periodic Table – Argon (Ar) is a chemical element that may be found on the periodic table. It is a noble gas from Group 18 and Period 3. Here’s how it looks on the periodic table:

Argon is found in Group 18, usually known as the noble gas group, according to the periodic table. Elements in this category have a complete outer electron shell, which makes them chemically inert or unreactive under normal conditions. Argon’s electron configuration of 1s2 2s2 2p6 3s2 3p6 allows it to have an outer shell with a total of 8 electrons, making it stable and non-reactive.

Because Argon is in Period 3, it possesses three electron energy levels or shells. It is found in Period 3 after chlorine (Cl) and before potassium (K). Argon is an element in the periodic table’s p-block, which includes elements from groups 13 to 18. It belongs to the table’s third period (row), which contains elements having three electron shells.

Argon Atomic Number

Argon has an atomic number of 18. This suggests that the nucleus of a neutral argon atom contains 18 protons. The atomic number is an element’s fundamental attribute that is used to identify and classify elements in the periodic table. Argon, with an atomic number of 18, occupies the 18th position in the periodic table, with other elements in Group 18, generally known as the noble gases.

how many valence electrons does argon have

Argon (Ar) has a valence electron count of eight. Valence electrons are electrons found in an atom’s outermost energy level (shell). The electron configuration of argon is 1s2 2s2 2p6 3s2 3p6. The third energy level (n=3) is the most outermost energy level, with 8 electrons altogether, which are the valence electrons. Because argon is in Periodic Group 18, it belongs to the noble gases, which have entire outer electron shells and are hence stable and unreactive.

how many neutrons does argon have

Subtracting the atomic number (number of protons) from the atomic mass (mass number) yields the number of neutrons in an argon (Ar) atom.

As previously stated, argon has an atomic number of 18 and an atomic mass of roughly 39.948 g/mol (this figure can fluctuate somewhat owing to isotopes, but we’ll take the average atomic mass here).

Number of neutrons = Atomic mass – Atomic number
Number of neutrons = 39.948 – 18
Number of neutrons = 21.948

Argon has roughly 22 neutrons when rounded to the next full number. Keep in mind that this value may differ for different isotopes of argon, however it is around 22 neutrons for the most common naturally occurring isotope.
