Question

Rounded to the nearest whole number, how many electrons are in an atom of zirconium? 40 51 91 131

Answer 1

The correct answer is 40

Answer 2

Answer: The number of electrons in an atom of zirconium are 40.

Step-by-step explanation:

Electrons are one of the subatomic particles present in an atom.

Electrons in an atom is judged by the atomic number of the atom.

Atomic number = Number of protons = Number of electrons

Atomic number of Zirconium = 40

Number of electrons will be equal to 40

Electronic configuration of Zirconium (Z = 40):
`1s^22s^22p^63s^23p^64s^23d^(10)4p^65d^24d^2`
