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'.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
