Does an ionic bonds is any bond that is made from ions?

No, An ionic bond is where two atoms (non metal and metal) are bound in order to more closely balance out the valence shell. For example, a negatively charged iron [extra electron(s), anion] and positively charged oxygen [loss of electron(s), cation] bond to increase atomic stability. This is through transfer of the electron (electrovalence) whereas its counter is covalent (sharing of the electron). That being said, the term ionic bond is used when the ionic character is larger than the covalent; giving a larger difference in electronegativity. Yielding electric conductivity potential

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
