An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess. You can find the number of neutrons if you know the isotope of the atom. Simply subtract the number of protons (t...
What is the atomic number of an element with 10 protons, 11 neutrons, and 10 electrons? a) 11 b) 21 c) 10 d) 31 What is the atomic number of an element with 9 protons, 10 neutrons and 8 electrons? A) 10 B) 19 C) 9 D) 28 ...
What will an atom do if it has 1 to 3 valence electrons? An atom of an element has 10 protons. what is also true of that atom? A single atom of an element has 11 protons, 11 electrons, and 12 neutrons. Which element is it?

The addition or removal of neutrons may change the property of an element, making it radioactive for example. But most of the time, chemists are concerned with the number of electrons each element have. A simple example would be sodium metal. In its atomic form, it has 11 electrons and ...
In terms of mass, we see that protons and neutrons are very similar with both having a mass of approximately 1 amu (atomic mass units). Now compare that to the mass of the electrons which are about 1,800 times less massive. As an analogy, if protons and neutrons had a mass around th...
