a)1s22s22p63s23p63d84s2 b)1s22s22p63s23p63d104s1 c)1s22s22p53s23p63d104s2 d)1s22s22p63s23p63d104s2

Answer is: D).

Zinc a chemical element (the group 12 of the periodic table) with symbol Zn and atomic number 30, which means it has 30 protons and 30 electrons, because atom has neutral charge.

Electronic configuration of zinc atom: ₃₀Zn 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s².

In compounds zinc usually has oxidation number +2.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
