When an anion forms, its atomic radius increases. This occurs because the addition of one or more electrons to the atom increases electron-electron repulsion within the electron cloud, causing the cloud to expand. As a result, the overall size of the ion becomes larger than that of the neutral atom.

Is br a anion or cation?
Br is an anion. It is called bromide and is the ion form of the element bromine.
Does the atomic number of the element change when its atom forms ion?
No. Atomic Number is defined as the number of positive protons, and when a ion is formed(irrespective of cation or anion) only negative electrons will be lost or added hence the proton number is constant.

The number and charge of lithium?
Atomic number of lithium: 3 Charge of the anion Li+1: +1
How does the size of the atomic radius in a nonmetal compare to size of its ionic radius?
I'm not positive but.... the ionic radius of a metallic atom is slammer than its atomic radius because metallic atoms want to loose electrons. The loss of electrons increases the pull of the nucleus, drawing the electrons closer and thereby making the ionic radius smaller than the atomic radius.
What is half the distance from center to center of two atoms bonded together?
The half distance from center to center of two atoms bonded together is known as the covalent radius, which represents half the distance between the nuclei of two bonded atoms. It is a measure of the size of an atom when it forms a covalent bond with another atom.

An atom that gains electrons and therefore forms a negative ion is known as a?
If an atom gains an electron it has a net negative charge and is known as an anion. A ion has a single atom which is atomic or monatomic.
The number and charge of lithium?
Atomic number of lithium: 3 Charge of the anion Li+1: +1
Is iron an anion or cation?
Iron forms a cation.
Does iodine form a cation or a anion?
Iodine forms the iodide ion. It has a charge of negative 1 (-1)
How is an ionic radius and an atomic radius related?
Ionasion energy decreases as the shielding effect increases , due to the fact that more electrons are available and less nuclear attraction takes place. Therefore lower ionasion energy will be required.
Who has the largest radius calcium atom or calcium ion?
The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.
