Atoms of which element contain 25 protons? magnesium (mg) aluminum (al) tin (sn) manganese (mn)

Manganese element has 25 protons.

Explanation:

Atomic number is defined as the number of protons or number of electrons that are present in an atom. It is represented as 'Z'

Z = Atomic number = Number of protons = Number of electrons

For the given options:

Option 1: Magnesium (Mg)

This element has an atomic number of 12, thus it will have 12 protons.

Option 2: Aluminium (Al)

This element has an atomic number of 13, thus it will have 13 protons.

Option 3: Tin (Sn)

This element has an atomic number of 50, thus it will have 50 protons.

Option 4: Manganese (Mn)

This element has an atomic number of 25, thus it will have 25 protons.

Hence, manganese element has 25 protons.
