An atom of the element chromium has an atomic number of 24 and a mass number of 52. how many electrons are in an uncharged atom of chromium? 0 24 28 52

Answer : The correct option is, '24'

Explanation :

Element = Chromium

Atomic number = 24

Mass number = 52

The electronic configuration of chromium atom is,

As per electronic configuration, the number of electrons are = 24

or,

Atomic number = Number of electrons = Number of protons

Mass number = Number of protons + Number of neutrons

As we know that the atomic number is equal to the number of electrons. So, the number of electrons in an uncharged atom of chromium are '24'.
