In general, it is a valence electron that an atom makes available to form chemical bonds.
Apex: A bond from the transfer of 1 or more electrons.
A hydrogen bond--two between A and T and three between G and C.
Carbon will normally form four covalent bonds.These are normally one of several possible hybridizationsof the s and p orbitals.
Covalent Bonds.
a weak hydrogen bond
Ionic bond.
which is not a type of chemical bond, covalent, electron, ionic, or hydrogen
With only 1 electron in its valence shell, the atom is likely to form an Ionic bond.
An ionic bond
A covalent bond is the strongest of the four types of chemical bonds, as it requires two atoms to share at least one electron each to form full electron shells.
ionic; it would donate one electron and carry a positive charge
An Ionic bond. When a metal (Potassium) and a non-metal (Chlorine) bond, they form an Ionic bond where the metal essentially donates some if it's valence electrons to complete the valence electron shell of the non-metal.
ionic bond
This is an ionic bond.
A valence electron
ionic bond
Single covalent bond. They share an electron pair.
