why is the nucleaus of an atom positivelty charged?
neutrons have no charge, so the atom is always positively charged
1 of 9
why do atoms have no overall charge?
an atom has no overall charge because it has the same number of positive protons and negative electrons so the charges cancel each other out.
2 of 9
what is an isotop
isotopes are atoms of the same element with the same atomic number but different mass numbers.
3 of 9
what is the realative charge of a proton?
+1, this is because protons are positive
4 of 9
what is the relative mass of a proton?
1
5 of 9
what is the relative charge of a neutron
0, this is because neutron are neutral
6 of 9
what is the relative mass of a neutron
1
7 of 9
what is the relative charge of a electron
-1, this is because lectrons are negative.
8 of 9
what is the relative charge of an electron
0.0005 (almost zero)
