Question

an atom X contains 13 protons, 14 neutrons and 10 electrons, it is ____​

Answer 1

Explanation:

may be the answer is aluminium.

Answer 2

Answer:

Aluminium

with valency = 3

and , mass = 27

Explanation:

Given ,

Number of protons = 13

Since ,

Atomic number = Number of proton

→Atomic number = 13

Now ,

atomic mass = No. of protons + No. of neutrons

→atomic mass = 13 + 14

→atomic mass = 27

Again , No. of electron = 10

Therefore ,

its valency = 13 - 10 = 3

Therefore , the element is ³Al
