If an element has 35 electrons and its mass number is 37, what is its atomic number and how many neutrons does it have?. Multi Line Text.

Respuesta :

Answer:

Atomic Number: 35

Number of Neutrons: 2

Explanation:

The number of protons and electrons are the same, so given that this element has 35 electrons, it also has 35 protons.

Atomic number is the number of protons, so it is 35.

Mass number is the number of protons + neutrons, so take the mass number of 37 and subtract the 35 protons to get 2 neutrons.
