determine the number of protons, neutrons, and electrons in an atom if given the atomic number and the mass number; also be able to determine in which electron shell the electrons will be found

1.) the number of proton = number of electron = atomic number

2.) mass number = number of protons + number of neutrons

3.) number of neutron = atomic numbet - mass number

Explanation:

example:CARBON

atomic number - 6

mass number - 12

protons - 6

electrons - 6

neutrons - 6

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
