What does atomic radius do across a period?
Atomic radius tends to decrease across a period from left to right. This is because as you move across a period, the number of protons in the nucleus increases, leading to an increase in the effective nuclear charge felt by the outermost electrons, which pulls them closer to the nucleus.
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 is the pattern of atomic mass as you go across a period?
As you move across a period in the periodic table from left to right, the atomic mass generally increases. This increase is due to the addition of protons and neutrons in the nucleus of the atoms, which raises the overall mass. However, the increase is not perfectly linear, as isotopes and variations in neutron numbers can cause slight fluctuations in atomic mass values.
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 size generally as you go down a group?
Atomic size generally increases as you go down a group
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?
Atomic size generally decreases as you move across a period from left to right due to increasing effective nuclear charge. However, atomic size tends to increase as you move down a group due to the addition of more electron shells.
How do atomic numbers and atomic masses increase in the periodic table?
Atomic numbers increase from left to right across a period on the periodic table. This is because each element in a period has one more proton in its nucleus compared to the element before it. Atomic masses generally increase from left to right as well, but there may be deviations due to isotopes or other factors. Within a group or column, atomic numbers and atomic masses increase from top to bottom as each successive element has more electrons and neutrons than the one above it.
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 number change in a period?
When going left to right across a period, the atomic number of element increases.
What is the pattern of atomic mass as you go across a period?
As you move across a period in the periodic table from left to right, the atomic mass generally increases. This increase is due to the addition of protons and neutrons in the nucleus of the atoms, which raises the overall mass. However, the increase is not perfectly linear, as isotopes and variations in neutron numbers can cause slight fluctuations in atomic mass values.
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.
From left to right across the second period of the periodic table?
The second period of the periodic table contains elements from lithium to neon, in increasing atomic number order. These elements have increasing numbers of protons and electrons as you move from left to right across the period, resulting in changes in properties such as atomic size and reactivity.
