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
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 16 nuetrons in phosphorus atom
there are 12 nuetrons in an atom of magnesium
The atom had:17 Protons18 Neutrons and17 Electrons(double-checked)
19 protons,21 neutrons
The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".
26 nuetrons, 22 electrons, and 22 protons
if an atom is electrically neutral it has twice as many nuetrons as it does protons and electrons.
it however has 15 protons , 15 electrons , and 16 nuetrons
