2024年5月28日 · Argon has an atomic number of 18, which corresponds to the number of protons, and an atomic mass of 40 (approx.), which is the sum of protons and neutrons. …

2024年5月25日 · Checking the Periodic Table for the element having an atomic number of 18, we find that it is argon. Argon's electron configuration is 1s2 2s2 2p6 3s2 3p6, which has all of its …

2024年5月31日 · In any neutral atom, the number of electrons is the same as the number of protons, and that is defined as the atomic number of the atom. The atomic number of argon is …

2024年6月17日 · The atomic number of an element is the number of protons in its nucleus. Since sulfur (S) typically has 16 protons, the atomic number of S-2 (sulfide ion) would be 16 + 2 = 18.

2018年2月2日 · Then, look at the top number of each element, and that is the atomic number. When you reach element number #18# on the periodic table, there should be an element with …

2024年6月17日 · The atomic number of sulfur is 16 The number of protons is the same as the atomic number. The S-2 gains 2 electrons so it changes from 16 to 18. The atomic mass is 32.

2024年5月28日 · The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. Therefore, the mass number of an atom with 18 protons and 22 neutrons is 18 + …
