Ionization energies tend to do what from left to right across a period?
increase from left to right across a period.
Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
What happens to the atomic radius as you go across a period?
It decreases as you move from left to right because there is an increase in positive charge in the nucleus as you go from left-to-right. Each time you go over an element it has one more electron and proton added to the principal energy level, so the nucleus pull increases and it holds the valence electron in tighter.
Atomic radius _moving from left to right across a period?
Decreases
What are the period and group trends in electronegativites?
The trends from left to right in a period increase (nuclear charge), and moving down a group decreases (shielding).
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
Atomic size generally as you go down a group?
Atomic size generally increases as you go down a group
Ionization energies tend to do what from left to right across a period?
increase from left to right across a period.
How does the atomic raduis change across a period of the periodic table?
Atomic radius usually decreases from left to right across a period of the periodic table.
Does elements on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.

How does the atomic number change in a period?
When going left to right across a period, the atomic number of element increases.
How does the atomic radius vary in a period?
Atomic radius decreases across a period from left to right, except for the noble gases.
What happens to the atomic radius as you go across a period?
It decreases as you move from left to right because there is an increase in positive charge in the nucleus as you go from left-to-right. Each time you go over an element it has one more electron and proton added to the principal energy level, so the nucleus pull increases and it holds the valence electron in tighter.

As you go from left to right across a period the atomic radii does what?
Increases
What are the period and group trends in electronegativites?
The trends from left to right in a period increase (nuclear charge), and moving down a group decreases (shielding).
