elements and atmoic structure

what is an element?

what does the atomic mass tell us about an element?

what does the atomic number tell us about an element?

describe the composition of an atom

what is the relative charge and mass of a proton?

what is the relative charge/mass of a neutron?

what is the relative charge/mass of an electron?

why does a neutral atom have the same number of protons and electrons?

why are electrons important in an atom?

how many electrons do each shell hold?

a chlorine atom has 17 electrons. how would we right this in short hand?

what does the number of electrons in the outer most shell tell us?

what does the number of shells filled tell us about an element?

why are noble gasses highly unreactive?

what must an atom be in order to have a full outer most shell? give examples of these types of atom

why do ions form?

if a metal bonds with a non metal, what happens (in terms of electrons moving)

what is the charge of a metal ion?

what is the charge of a non metal ion?

what is the structure of an ion the same as?

sodium's atomic number is 11.
now many protons does it have? why?

sulfur's atomic number is 16.
a)what is it's electronic structure?
b)what is the structure of the nearest noble gas?
c)what is the electronic structure of the ion?
d)what is the overall charge?

how would you find the charge of a metal ion?
a non metal ion?

name 5 ions with the charge '+'
