I don't know because the statement is (in general) NOT true. Who told you so?
For instance:
KMnO4, in which the central Mn has 7 bonds: one single (-) and three double (=) bonds, binding 4 other atoms (O).
(K-O-)Mn(=O)3
Any atom with more than one bonding site will form multiple bonds.
The outer electrons of a metal atom that bonds with a nonmetal atom are either transferred to the nonmetal to form an ionic bond or shared with the nonmetal to form one or more covalent bonds.
Theoretically, in extreme conditions, every atom can form every type of bonds. Generally, atoms tend to bond each other by releasing the most possible energy. The lower the energy of the bond is the more stable.
Two bonds between the two oxygen atoms in O2. Three bonds between the two nitrogen atoms in N2

Any atom with more than one bonding site will form multiple bonds.
A carbon atom can typically only form 4 covalent bonds, but there are rare special cases in which it may form more than 4 to create an expanded octet.
They can form Double Bonds, or bond with more than one atom at a time.
No: A carbon atom has only four valence electrons and therefore can form no more than four covalent bonds.
How many bonds can atom form? not have ok so its answer is atoms are polygomus..they can make as many bonds as they desire . By its valence number. Remember the octet rule, atoms form bonds in order to have eight electrons in their outer shell (with the exception of hydrogen and helium.) Atoms can form multiple covalent bonds if they need more than one electron to complete their valence shells. Oxygen, for example, bonds with itself to form 2 bonds between the atoms (since each atom needs to share 2 electrons). i have given three answers so ithink you can now better understand
ionic bonds form when one atom gains electrons or loses electrons to another atom covalent bonds form when one 2 atoms share electrons in both types of bonding atoms bond to become more stable (to become similar to noble gases by filling their outer most shell)
An atom that has fewer than 8 valence electrons is more reactive, or more likely to form bonds, than an atom with 8 valence electron. Atoms bond by gaining, losing, or sharing electrons in order to have a filled outermost energy level with 8 valence electrons.
The outer electrons of a metal atom that bonds with a nonmetal atom are either transferred to the nonmetal to form an ionic bond or shared with the nonmetal to form one or more covalent bonds.
It can only make three bonds. Boron has three valence electrons and therefore cannot form more than three bonds with no lone pairs.
Because forming more than four bonds would give the atom more than 8 valence electrons

Ionic (be careful with that spelling!) bonds form through the transfer of one or more electrons from one atom (the cation) to another (the anion). Covalent bonds occur when the electrons are "shared" by two atoms.
