What happens to the number of electrons as the atomic number increases on the period table?

The electrons increase, too.
The atomic number is the number of protons, which gives the positive charge ( a more useful number than the atomic weight ), to balance the positive charge, a roughly equal number of electrons are needed. There are minor differences in some molecular combinations, and some temporary imbalances, but generally the charges balance out.

∙ 12y agoAs the atomic number increases (indicating the number of protons) the number of electrons in a neutral atom will always be exactly the same number.
The radii of these atoms (the extent of the electron shells) will vary as the respective orbitals are filled.

What happens to the number of electrons in an atom when the atomic number increases?
The atomic number is specific to the element itself - not the quantity. It does not change as you add in more of the element.
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 are the two variables that affect atomic size within a group?
Increase in positive charge draws electrons closer to the nucleus. Increase in the number of occupied orbitals shields electrons in the highest occupied energy level from the attraction of proteins in the nucleus.
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 atomic numbers?
Atomic numbers are the number of protons and electrons in a atom.

What does the number of electrons in an atom do as the atomic number increases?
Increase
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
What happens to electrons when you move from left to right across a period?
I think you are talking about electroNEGATIVITY. It increases as move from left to right and increases from bottom to top. Check out Fluorine, it has the highest electronegativity, about 4.00
What happens to the atomic number as you move across a period?
.The atomic mass increases
What happens to the electron configuration as the atomic number increases?
the elctron configuration increases
What happens to valence electrons as you move across the row?
The number of valence electrons increases.
What happens to the atomic number as you go across a period?
The atomic number increases as one go across a period.
What happens to the atomic number as you go down the group?
Atomic number increases down the group and along the period as well.
What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
The number of valence electrons increases with increase in what from the beginning to the end of period 2?
The number of valence electrons increases with increase in atomic number from the beginning to the end of period 2. The maximum number of valence electrons possible in any outermost shell is 8.
Does the atomic number equal the amount of neutrons?
no, the atomic number, for the most part, is how much protons and electrons there are. The number of neutrons is determined when you subtract the atomic number from the atomic mass. When chemical bonding happens however, the number of electrons and protons could differ.
