Answer 2

Answer:

mark me as brainliest

Explanation:

a. Sodium is a chemical element with the symbol Na and the atomic number  11 It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged ion—the Na⁺cation

The electronic configuration of sodium is given as 1s22s22p63s1

b.Potassium is forst element of period 4. Electronic configuration of potassium is 1s22s22p63s23p64s1 and also [Ar]4s1 where [Ar] is 1s22s22p63s23p6
