What else can I help you with?
Why does atomic size increase from left to right across a period?
atomic size decreases across a period
Why does the change for the atomic radii of the elements for period 3 from sodium to argon look similar to period 2?
Because the trend is the same. Atomic radius decreases from left to right across a period.
What happens to the atomic number as you move across a period?
.The atomic mass increases
What is the trend in atomic size across the period from sodium to argon?
Atomic size decreases across the period from sodium to argon due to increasing nuclear charge, which attracts the outermost electrons more strongly, pulling them closer to the nucleus. This results in a smaller atomic size as you move from left to right across the period.
Atomic radius _moving from left to right across a period?
Decreases
How does the atomic number change in a period?
When going left to right across a period, the atomic number of element increases.
Why does atomic size increase from left to right across a period?

Why does the change for the atomic radii of the elements for period 3 from sodium to argon look similar to period 2?
Because the trend is the same. Atomic radius decreases from left to right across a period.
What happens to the atomic number as you go across a period?
The atomic number increases as one go across a period.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
How does the atomic raduis change across a period of the periodic table?
The atomic radius generally decreases across a period of the periodic table from left to right due to increased nuclear charge pulling electrons closer to the nucleus. This results in a stronger attractive force, leading to a smaller atomic radius.
How does size change in a period and in a group?
Atomic size decreases across a period as the effective nuclear charge increases. Atomic size increases down a group as the energy level (shells) increases.
How does electronegativity change across the period?
Electronegativity tends to increase across a period from left to right. This is because as you move across a period, the nuclear charge increases and the atomic radius decreases, leading to a stronger attraction for electrons by the nucleus.
What happens to the atomic number as you move across a period?
.The atomic mass increases
What is the trend in atomic size across the period from sodium to argon?
Atomic size decreases across the period from sodium to argon due to increasing nuclear charge, which attracts the outermost electrons more strongly, pulling them closer to the nucleus. This results in a smaller atomic size as you move from left to right across the period.
What decreases across the periodic table?
Atomic size decreases across a period
Why does the change for the atomic radii of elements in period 3 from sodium to argon look similar to period 2?
The atomic radii of elements in period 3 from sodium to argon decrease due to a greater nuclear charge pulling electrons closer to the nucleus. This trend is similar to period 2 because both periods follow the same pattern of increasing nuclear charge as you move across the period, leading to a similar decrease in atomic radii.
