How many neutrons does the element Sc have?

Answer 1

The atomic number of scandium is 21. So it has 21 protons and 21 electrons.

Number of neutrons depends on the isotope.

Number of neutrons = Mass number - Atomic number

Sc-45 isotope has 24 neutrons

Answer 2

There are 21 electrons in a neutral atom of the element scandium.

Answer 3

21 Protons

Protons are the same as the atomic number so Scandium's atomic number is 21 therefore Scandium has 21 protons

Answer 4

that's easy....it's 24 neutrons....cuz it's 45(the Atomic Mass) - 21 ( the # of protons/ atomic number)

Answer 5

scandium has 24 neutrons

Answer 6

Scandium has 21 protons.

Answer 7

Scandium has 24 neutrons.

Answer 8

21
