Question

An atom has 16 protons and 16 neutrons. Which of the following could be the symbol for that atom, including its mass numbe? Consult the periodic table.
A. 35CL
B. 32S
C. 32Cl
D. 35S

Answer 1

the atomic mass is 32.066. and the answer is B and the name is sulfur 

Answer 2

Answer:

Option b. 32S

Explanation:

Given:

No. of protons = 16

No. of neutrons = 16

Atomic number of an element is equal to the number of protons present in it.

Therefore, atomic number of the element = 16

Mass number of the element is equal to sum of number of protons and neutrons.

Therefore, Mass number = 16 + 16 = 32

Element 'S' has atomic number 16 and its mass number is 32.

So among the given options, option b is correct.
