Tetrahedral
Trigonal planar
Trigonal bipyramidal
This is based upon the number of protons in the atom's [or ion's] nucleus: it's atomic number. Protons possess one positive charge, normally balanced or offset by the negative charge possessed by an electron.
The 6 domains of life are archaebacteria, eubacteria, fungi, Protista, plantae, and animalia. What makes each domain different is the purpose in which they serve in relation to how life is created.

3 bondings + 1 electron pair = 4 (electron domains)
Because there are 2 bonded and 2 unbonded electron domains. since there are 4 electron domains, its original form would be a tetrahedral. however, for the molecular, you must remove to two unbonded domains, leaving the two domains as far apart from each other as possible
?
true
There are three domains (Bacteria, Archaea, Eukarya) and six kingdoms (Animalia, Plantae, Fungi, Protista, Archaea, Bacteria) in the modern system of taxonomy.

electron domains in the valence shell of an atom will arrange themselves so as to minimize repulsions
With 4 valence electrons, carbon has many electron domains, allowing it to hybridize those electron domains. Additionally, with a fairly small atomic radius, carbon is able to form single (sigma) bonds, but also double and triple (pi) bonds, due to overlapping electron orbitals. This gives carbon many bonding options, which in turn makes it a fine choice as a fundamental element in organic compounds.
