What happens to the outer electron shell as you move to the far right of a period?

On the periodic table, first ionization energy generally increases as you move left to right across a period. This is due to increasing nuclear charge, which results in the outermost electron being more strongly bound to the nucleus.

How does the number of electrons in the outer shell change as you move across the periodic table?

As the atomic number increases along each row of the periodic table, the additional electrons go into the same outermost shell, causing the atomic radius to decrease due to the increasing nuclear charge.

Does the number of outer shell electrons increase across a period?

In a period from left to right the number of valence electrons in the same shell increases.

What happens when the shell number increases?

The general trend is – as the atomic number increases, the size of the atom decreases. This is due to the fact that the new electrons enter into the same shell in each of the rows.

How many electrons are in the outermost shell of bonded atoms that follow the octet rule?

The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.

When electrons are removed from the outermost shell of a calcium atom?

When the valence electrons are removed, calcium reverts to a [Ar] configuration.

How many outer shell electrons does group 1 have?

one electron
The atoms of all group 1 elements have similar chemical properties and reactions because they all have one electron in their outer shell. Similarly, the atoms of all group 7 elements have similar chemical properties and reactions to each other, because they all have seven electrons in their outer shell.

Which one increases with increasing number of shell?

atomic orbitals
As number of shells increases, atomic orbitals become smaller and more stable.

What happens to the number of electrons shells as you go down a group?

The number of electron shells is therefore the same across a period but increases when moving down a group.

Why does the outermost shell have 8 electrons?

The maximum capacity of a shell to hold electrons is 8. The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. This is a very important rule called the Octet rule.

What happens to the size of atoms as the number of electrons increases?

This is because of the reason that if the no. Of electrons increases then there would be more electrostatic force between the shells and the nucleus thus as the no of electrons increases from left to right period wise the electrostatic force also increases and thus the size of the atoms decreases. 697 views.

How does the number of filled electron shells change across periods?

Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases. Moving down a group in the periodic table, the number of filled electron shells increases.

How does the radius of an atom change across a period?

Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.

How does atomic number affect the number of shells in atoms?

When we go top to bottom in a group, the number of shells in an atom increases as the atomic number is increasing. Also the effective nuclear charge I,e the force of a proton per electron also decreases. Protons are now unable to hold the electrons tightly. Therefore the shells are more farther off than in lighter atoms.
