Question

The atomic number and mass number of an atom x is 13 and 27 respectively. How does it express along with its symbol? find the number of protons and neutrons in this atom?​

Answer 1

Answer:

al(alluminium) it has 13 protons and 14 neutrons

Explanation:

Answer 2

Answer:

X : Z = 13 and A = 27 .

We generally write the mass number as the superscipt and atomic number as subscript .

Mass number is the sum of protons and neutrons , i.e. , nucleons . Atomic number is the number of protons in an atom.

Therefore , Protons = Z = 13.

Neutrons = A - Z = 27 - 13 = 14 .

Hope this helps .

Have a nice day !
