A neutral atom has 37 electrons. How many protons does the atom have?
a more than 37 protons
bless than 37 protons
C exactly 37 protons
d it is impossible to know without more information

It's answer is c) exactly 37 protons

C) ,  Exactly 37 protons.

Explanation:

Remember the electrons have a negative charge, so to make a atom with 37 electrons neutral, you will need the same amount of the opposite type. That means you need 37 protons.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
