Question

If an element M has mass number 24 and atomic number 12, how many neutrons does its atom contain and also find how many electrons and protons?​

Answer 1

• Mass number =24
• Atomic number=12

Number of protons=Mass number=12

Number of electrons=number of protons=12

Number of neutrons:-

$\\ \sf\longmapsto Mass\;Number-Number\:of\:protons$

$\\ \sf\longmapsto 24-12$

$\\ \sf\longmapsto 12$

Answer 2

Explanation:

Atomic mass= proton + neutron

Atomic number= number of protons or number of electrons

note-(electrons only in case of a neutral atom)

As atomic number=12

no of protons=12

As atomic mass is number of proton + number of neutron

and number of protons is 12

so number of neutrons is also 12

therefore-

PROTONS=12

NEUTRONS=12

ELECTRONS=12

for your knowledge this atom is Mg(Magnesium).
