As you travel down a group the do atomic size increases or decreases?

it increases: for the atomic number indicates the number of protons and neutrons in the atom; these are the weight carrying particles

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 is the trend in atomic radius down a group explain?
the atomic radii increases down the group.
Why has bromine got a bigger atomic radius than iodine?
Bromine has a SMALLER atomic radius because it has one more electron shell than Iodine. On the periodic table, atomic radius of an atom decreases across a period and increases down a group. Since Bromine and Iodine are in the same group, you know Bromine has a smaller atomic radius because it is in a lower period.
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.
What pattern in atomic size occurs in the periodic table?
In the periodic table, the atomic size increases with every period due to addition of an extra shell. The atomic size decreases with every group since no. of electrons and protons are increased with every group across a period leading to extra electrostatic force of attraction between electrons and the nucleus and thus shrinking the size of the atom.
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 increases down a group and decreases across a period?
Atomic radius
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.
How does size change in a period and in a group?
Atomic size decreases across a period as the effective nuclear charge increases. Atomic size increases down a group as the energy level (shells) 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 group 1 elements as you go down the table?
As you go down group 1, the atomic number and atomic mass increase. Electronegtivity decreases and 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 is the Atomic polarizability trend?
The Atomic polarizability increases top to bottom i.e down the group and it decreases left to right . This trend is the same as atomic radius .
What is one way atomic radius can be defined?
idk if this is an answer but this is what i found in my book. atomic raduis increases down a group and decreases across a period
How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
What are two trends in the periodic table?
Atomic size decreases from left to right in a period hence ioniztion energy increases from left to right.But atomic size increases from top to bottom in a group hence ionization energy decreases from top to bottom.
Vertical columns in the periodic table indicate what information?
its called a family or group or both of them.
