Does the radius of the atom increase if you increase the number of electrons?
What affects atomic radius?
Does increasing the number of protons decrease atomic radius beause of nuclear attraction (if yes doesnt this question contradict with the first question as the number of protons and electrons are equal)?

2. Nuclear attraction, number of shells. Might be some other stuff,but I can't think of anything right now.
3.Most the time. As you say, when you increase the number of protons the number of electrons increase also, which increases the nuclear attraction between the outer shell and the nucleus and hence decreases the atomic radius. However, the first electron on a new shell will not increase the nuclear attraction since there is more electron shielding etc. so group 1 elements have larger atomic radii than the group 8/0 of the period before.
Hope that's clear

1. Depends how many electrons are added and which orbital
2. Radius is affected by number of electron shells and number of protons
3. Yes
