When the atomic number increases what happens to the atomic radius?

When an electron absorbs a photon and therefore has more energy, it will move to a higher orbital and the radius of the atom will increase. This is generally a temporary state of affairs, since the electron will eventually re-emit the photon and fall back to its ground state.

∙ 12y agoIn the Periodic Table, atomic radii increase as you go to the left and decrease as you go up. This means Francium would have the largest atomic radius and Fluorine the smallest. This is due to the ratio of protons in the nucleus compared to electrons in the valence shell and the number of energy levels between the nucleus and the valence level.

What is the process that results in the increase of atomic number?
The number of energy levels increase within a group. Therefor the atomic radius increases. So the atomic volume also increases.The atomic radius also increases in a group.For metals, reactivity increases down the group. For non-metals, reactivity decreases down a group.
When atoms gains electrons what happens to the atomic radius?
The negative ionic radius is larger than the neutral atomic radius
What trend in atomic radius do you see as you go down a group on the periodic?
The atomic radius of elements increases as you go down a group. This increase in radius as you go down a period is primarily caused by the increasing principal quantum number of the outer electron shells.
What is the trend in atomic radius down a group explain?
the atomic radii increases down the group.
How does atomic number change as you move from left to right?
I'm guessing you are acking Atomic Radius. The atomic radius decreases and you go left to right because the shielding effect from the lower electrons stays almost constent while the elements gain more protons adding to the effective nuclear charge pulling the electrons closer to the nucleus.
When you go left to right on the periodic table what happens to the atomic radius?
Yes. The atomic radius increases down the group. This is because number of shells increases down the group.
What happens to atomic radius as you move from bottom to top of the periodic table?
atomic radius decreases from bottom to top of the periodic table.
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
How does atomic radius increases in the periodic table?
atomic radius increases down a group as the number of shells increases
What physical trends for atomic number versus covalent radius?
Overall as atomic number increases covalent radius increases.
What is the process that results in the increase of atomic number?
The number of energy levels increase within a group. Therefor the atomic radius increases. So the atomic volume also increases.The atomic radius also increases in a group.For metals, reactivity increases down the group. For non-metals, reactivity decreases down a group.
What happens to the atomic radius as the atomic number increases?
Going across a row in the peiodic table, the atoms have more protons and electrons causing a stronger attractive force, pulling the electrons closer to the nucleus, making the atomic radius decrease. As a new shell is added ( next row down) the atomic radius increases
How does atomic radius vary in group and in period on periodic table?
Down a period the atomic radius increases as the number of shells (or energy levels) increases. Across a period the atomic radius decreases as the effective nuclear charge increases.
What property increases going down the periodic table?
Your question is incorrect. It should be increases rather than decreases. Well it is the proton number (Z) that increases.
What is the Group trend Atomic radius?
Atomic radius increases down the group. This is because of the increase in number of shells.
When moving left to right across the periodic table the atomic number increases and the atomic radius?
The atomic radius decreases from left to right and increases from top to bottom
Why does the atomic radius decreases as the atomic number increases?
The atomic radius decreases as the atomic number increases due to the fact that there is now a greater quantity of protons in the nucleus emitting greater intramolecular force, pulling the electrons closer towards it. This, thus, decreases the radius.
