Increase in positive charge draws electrons closer to the nucleus. Increase in the number of occupied orbitals shields electrons in the highest occupied energy level from the attraction of proteins in the nucleus.
The number of protons in the nucleus is the principal factor.
1-as the atomic number increases within a group 2-the charge on the nucleus increases and the number of occupied energy level increases.

Water is one of the main environmental variables that can affect the size of a population. For a population to thrive water must be both available and safe for drinking.

age, size, and physical activity
Alkali metals and noble gases
Exposure, Particle size, mineral composition, & climate.
not counting variables such as wind resistance and such, no
group size has a negligible effect on performance characteristics and a strong effect on member reaction
Ionic size increases from top to bottom within the group.
In general, atomic size increaes from top to bottom within a group and decreases from left to right across a period.
