The atoms of the elements in Group 13 (IIIA), the boron group, have three valence electrons, all of which are unpaired. The atoms of the elements in Group 15 (VA), the nitrogen group, have five valence electrons, three of which are unpaired.
The Noble gas group all have 8 valence electrons.
Ionic bonds form during chemical changes when atoms pull electrons away from other atoms. The atoms that lose electrons form ions that have fewer electrons than protons. So, an ion would be produced by an atom or a group of atoms that gained or lost one or more of its electrons.
atoms in a group have the same number of valence electrons
No it does not.
All of the elements in group 17/VIIA, known as the halogens, will react the same as chlorine, a member of this group. All halogen atoms have 7 valence electrons, so they will form ionic bonds or covalent bonds to get 8 valence electrons.
The atoms of the elements in Group 13 (IIIA), the boron group, have three valence electrons, all of which are unpaired. The atoms of the elements in Group 15 (VA), the nitrogen group, have five valence electrons, three of which are unpaired.
It is the halogen group. They are in the P block.

The number of electrons in a neutral atom is equal to the atomic number.
Atoms in the same group (in the same vertical column) of the periodic table have the same number of electrons in their outer shell. A neutral atom has the same number of electrons as it has protons. The number of protons is given by it's atomic number. The electrons are considered to be arranged in "shells." The outermost shell can have from 1 to 8 electrons. The effect of being in the same group is that the atoms within a group have similar reactions.
The Noble gas group all have 8 valence electrons.
Ionic bonds form during chemical changes when atoms pull electrons away from other atoms. The atoms that lose electrons form ions that have fewer electrons than protons. So, an ion would be produced by an atom or a group of atoms that gained or lost one or more of its electrons.
