there are 12 protons in an atom of magnesium:-)
protons and nuetrons are equal to no. of electrons present in atom
Neutrons: 6 Protons: 6 Electrons:6
it has 35 nuetrons, 30 protons, and 30 electrons with a mass of 65
Number of Protons & Electrons: 47 Number of Nuetrons: 61 http://www.purestcolloids.com/silver-atom-structure.htm
since there are 22 protons there has to be 22 nuetrons since there are 22 protons there has to be 22 nuetrons
there are 12 nuetrons in an atom of magnesium
A helium atom has 2 protons, 2 neutrons, and 2 electrons.
The atom had:17 Protons18 Neutrons and17 Electrons(double-checked)
19 protons,21 neutrons
26 nuetrons, 22 electrons, and 22 protons
The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".
it tells us the number on the Periodic Table and it also tells us how many protons and nuetrons and electrons are in the atom within the nuecles.
