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.
How do you account for the general trend in atomic radius across a row of elements?
The general trend in atomic radius across a row of elements decreases from left to right due to increasing effective nuclear charge, which attracts the electrons closer to the nucleus. As you move across a period, the number of protons in the nucleus increases, resulting in a stronger pull on the electrons and a decrease in atomic radius. Additionally, the shielding effect of inner electrons remains relatively constant, further contributing to the trend.
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?
The trend for ionic radius across the metals is that as you move down a group on the periodic table, the ionic radius increases. This is because as you go down a group, the number of electron shells increases, leading to larger atomic size and hence larger ionic radius.
What is the trend in ionic radius from left to right within a period?
The trend in ionic radius from left to right within a period generally decreases. This is because as you move across a period, the number of protons in the nucleus increases, leading to a stronger attraction for the electrons and causing the outer electron shell to be pulled closer to the nucleus, resulting in a smaller ionic radius.

How does calcium's atomic radius compared to magnesium radius and potassium radius?
The atomic radius of calcium is larger than magnesium but smaller than potassium. This trend is consistent with the periodic trend across Group 2 elements where atomic radius increases down the group due to additional electron shells. Additionally, going across a period from left to right, atomic radius decreases due to increasing nuclear charge pulling electrons closer.
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
What is is the trend across a period?
The trend across a period refers to how a property of elements changes as you move from left to right across a row in the periodic table. For example, in terms of atomic size, the trend across a period is generally a decrease due to the increasing number of protons in the nucleus pulling the electrons closer.
How does calcium atomic radius compare to magnesiums radius and potassiums radius?
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
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.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
What has the smallest atomic radius Na Mg Cl Al?
The smallest atomic radius is found in Cl (Chlorine), followed by Al (Aluminum), then Na (Sodium), and finally Mg (Magnesium). The trend typically follows an increase in atomic radius from right to left across a period and from top to bottom down a group on the periodic table.
