yes thank you

my question to you is, does the atom have more electrons than protons? and how do you know?

anonymous · Answer

i don't know anything about the atom the question doesn't specify

remember @daniellamontanez the number of protons always equals the number of electrons so the net charge would be 0

Take the example below. If i have an element with 3 electrons, I know that it has three protons. for any element the net charge when we add up the number of protons and neutrons is going to be zero.

but if I added 3 electrons. 

the net charge would be -3 

can you see why?
