atomic number of elements are the number of protons
in neutral atoms number of protons are equal to number of electrons
electrons are responsible for the chemical bonding in atoms
bonding depends on the number of valence electrons in the outermost shells.
atom A with 11 protons have 11 electrons, electronic configuration is - 2,8,1
atom B with 17 protons have 17 electrons, electron configuration is - 2,8,7
A has 1 valence electron and B has 7 valence electrons
therefore A prefers to give away its one valence electron and have a complete outer shell and B prefers to take in that one electron from A to become a complete octet.
The type of bond is an ionic bond formed by the transfer of electrons from one species to another species
answer is ionic
