Atoms increase in size as you go down a column and are larger going from right to left across a row.
because while going from left to right in a period electrons enter in the same orbit and hence the attraction between the nucleus increasees

∙ 12y agoGoing across a period, the ionic radius decreases for metals forming cations, as they lose their outer electron orbit. for non-metal atoms, the ionic radius increases as the effective nuclear charge is decreased due to having more electrons than protons.
As with all atomic radii, ionic radii increases going down a group.
For +ve ions of the same element, ionic radii decreases with increasing positive charge
For -ve ions of the same element, ionic radii increases with increasing negative charge

Ionic radius decreases across a period due to increase in nuclear charge.
Atomic radius decreases through a period. Atomic radius increases down a group. Helium has the least atomic radius.

WHAT BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
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 is the trend in atomic size across the period from sodium to argon?
across a period, the atomic size decreases as the effective nuclear charge increases.
Why is Mg smaller than Cl?
Magnesium isn't smaller than chlorine, it's larger. The atomic radius for magnesium is 145 pm and the atomic radius for chlorine is 79 pm. Both magnesium and chlorine are in the third period of the periodic table. The trend for atomic radius is that the elements generally get smaller as you move from left to right across the table in the same period.
What trend in ionization energy occurs across a period on the periodic table and why?
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
What is the trend for ionic radius for medals?
if you mean metals ..... for the same valence the radius decreases across a period and increases down a family
What is the trend in ionic radius from left to right within a period?
Atomic radius
What trend in ionization energy do you see as you go across a period row on the periodic table what causes this trend?
It is a trend in itself, it isn't caused by a trend.
WHAT BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
What is is the trend across a period?
what is the reason for ionization energy 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.
Why does the change for the atomic radii of elements in 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 trend does the atomic radius along a period on the periodic table?
The atomic radius decreases along a period. It is because of increasing effective nuclear charge along a period.
How does Electronegativity trend across the periodic table?
Electronegativity increases across a period (left to right).
What is the trend in atomic size across the period from sodium to argon?
across a period, the atomic size decreases as the effective nuclear charge increases.
Why is Mg smaller than Cl?
Magnesium isn't smaller than chlorine, it's larger. The atomic radius for magnesium is 145 pm and the atomic radius for chlorine is 79 pm. Both magnesium and chlorine are in the third period of the periodic table. The trend for atomic radius is that the elements generally get smaller as you move from left to right across the table in the same period.
What trend in ionization energy occurs across a period on the periodic table and why?
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
