Horizontally: decreasing from left to right.Vertically: increasing from top to bottom.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
The atomic radius decreases.
The atomic radius decreases.
Along a period, nuclear charge increases. hence, atomic radius decreases.
atomic radius decreases from bottom to top of the periodic table.
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
Across a period (horizontal), atomic radius decreases due to increasing nuclear charge pulling electrons closer. Down a group (vertical), atomic radius increases due to the addition of new energy levels further from the nucleus.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
The atomic radius decreases.
The atomic radius of gallium is about 135 picometers. In the periodic table, gallium has a larger atomic radius compared to elements to its left and a smaller atomic radius compared to elements to its right.
The atomic radius decreases.
Along a period, nuclear charge increases. hence, atomic radius decreases.
Along a period, nuclear charge increases. hence, atomic radius decreases.
Cesium will have a larger atomic radius than magnesium. This is because atomic radius tends to increase down a group in the periodic table, and cesium is located below magnesium in the periodic table.
The atomic radius of iodine is larger than the atomic radius of potassium. This is because as you move down a group in the periodic table, atomic size increases due to the addition of more electron shells. Iodine is located below potassium in the periodic table, hence it has a larger atomic radius.
atomic radius increases down a group as the number of shells increases
Silicon has a larger atomic radius than bromine. This is because as you move down a group on the periodic table, atomic radius tends to increase. Bromine is located further to the right on the periodic table and has a smaller atomic radius compared to silicon.
