a model that describes the three dimensional arrangement of electrons based on electron repulsion is called the model.
two hydrogen atoms form a when they have covalent bonds.
diamond and graphite are two of carbon.
resonance show the same connection of atoms but different arrangements of the bon
an atom that has less than eight electrons surrounding it in a compound is said to be
the number of outermost electrons is the number of

Explanation:

1. The VSEPR (Valence - Shell Electron - Pair Repulsion) model is used to describe the three - dimensional arrangement of electrons based on electron - electron repulsion.
2. Two hydrogen atoms form a duet when they have covalent bonds as hydrogen only needs 2 electrons to achieve a stable configuration.
3. Diamond and graphite are allotropes of carbon, which are different forms of the same element in the same physical state.
4. Resonance structures show the same connection of atoms but different arrangements of the bonds.
5. An atom with less than eight electrons surrounding it in a compound is electron - deficient.
6. The number of outermost electrons is the number of valence electrons.

Answer:

1. VSEPR
2. duet
3. allotropes
4. structures
5. electron deficient
6. valence electrons
