Question

The atom of an element has 16 neutrons and 14 electrons. What are the atomic number, valency and mass number ? class 9​

Answer 1

Answer:

M

Explanation:

The given element is having 14 nutrons and 27 mass number means number of electrons or protons are (z−n) 27−14=13 each.

Distribution of electrons according to 2n

2

(n = principal quantum number) is 2(K),8(L),3(M). Hence, the valence shell of this element is M.

Answer 2

Answer:

Atomic no. - 16, Mass number = 32 Valency = -2
