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
What else can I help you with?
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
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.
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.
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
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 physical trends for atomic number versus covalent radius?
As the atomic number increases within a period (row) on the periodic table, the covalent radius generally decreases due to increasing nuclear charge pulling the electrons closer to the nucleus. Within a group (column), as the atomic number increases, the covalent radius tends to increase since new electron shells are being added, leading to a larger atomic size.
What happendS to atomic radius as u go down the periodic taBLE?
the atomic radius increases down the periodic table as the number of shell (or energy level) increases.
What is the process that results in the increase of atomic number?
The process that results in the increase of atomic number is nuclear fusion. This occurs when two atomic nuclei combine to form a heavier nucleus, leading to an increase in atomic number. Nuclear fusion is the process that powers the sun and other stars.
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
