protons are positively charged and has a mass of 1, electrons are negatively charged and has a mass of 1/1835, and neutron has no charge and has a mass of 1
1 of 7
Why do atoms have no overall charge
Atoms have the same protons and electrons, this means there charges cancel out
2 of 7
Why is the most of the mass of an atom found in its necleus
because electrons have very little mass
3 of 7
What does the atomic number tell you about an element
how many protons is in that element
4 of 7
How can you describe and identify a isotope
they have the same atomic number but a different mass number
5 of 7
why are tthe relative atomic masses for some elements not whole numbers
it is the mean of all the isotpoes
6 of 7
How do you calculate the relative atomic mass of an element
