The element is Argon. Its configuration is 2 8 8.
Iodine is a non metal element. Atomic number of it is 53.
The chemical element with the atomic number 41 is niobium; the electron configuration is:[Kr]4d4.5s1.
You should use atomic number for electronic configuration. Atomic number represents the number of protons in an atom, which determines the element's identity and the number of electrons it typically has. Atomic mass number is the sum of protons and neutrons, which is useful for determining the mass of an atom but not for electronic configuration.
[Ar]3d34s2 is the shorthand electron configuration for Vanadium (V).
Each column will generally have the symbol of the element (sometimes name of the element also), the atomic number, the mass number, the state in which the element is present at room temperature. Some periodic table will also have the electronic configuration or electronegativity.
The electron configuration of cobalt is [Ar]3d7.4s2.
Ce, cerium. Electronic configuration [Xe]4f15d16s2
The electronic configuration of chlorine is 1s2, 2s2 2p6, 3s2 3p5.
The element calcium (atomic number 20) has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 or in noble gas form : [Ar] 4s2
Atoms of the element sodium (atomic number 11) have the electron configuration 1s22s22p63s1 with the noble gas form [Ne] 3s1
