As you go down the columns of the periodic table the number of protons (and electrons) in the element increase. As the atomic number increases, so does the radius at each electron shell.
The larger the highest energy level, the larger the atomic radius.
Atomic Mass
atomic radius decreases from bottom to top of the periodic table.
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
Atomic radius increases down a group due to increase in number of shells. Its value decreases along a period due to increase in nuclear charge.
Decreases. Look at the images under atomic radius, on wikipedia.
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
The larger the highest energy level, the larger the atomic radius.
the atomic radius decreses from left to right in periodic table due to increase in the number of succesive element the electrons of the outermost shell are more attracted towards nucleus and the atomic radius or atomic size decreases.
the larger the highest energy level number, the larger the atomic radius (Apex)
The atomic radius generally increases as you move down a column in the periodic table. This is because each successive element has an additional energy level, leading to larger orbits for the electrons and an overall increase in atomic size.
The larger the highest energy level, the larger the atomic radius.
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.
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.
Atomic Mass
The atomic radius of argon is smaller than the atomic radius of krypton. This is because as you move down a group on the periodic table, the atomic radius tends to increase due to the addition of extra electron shells. Argon is located above krypton in the periodic table, so it has a smaller atomic radius.
atomic radius decreases from bottom to top of the periodic table.
