The Lewis dot model of a molecule is shown. A visual diagram of a CH2O molecule is shown. Carbon is the central atom with two horizontal lines connecting to the oxygen atom on its right. The oxygen atom also has two pairs of dots around it. Carbon has two horizontal lines each connected to each of the two hydrogen atoms.

Based on the model, which of the following is true?

Oxygen is the least electronegative of the three atoms.
Carbon has a total of four bonded pairs of electrons around it.
Oxygen has four pairs of non-bonding innermost shell electrons.
Carbon has an incomplete octet as it transfers an electron to each hydrogen.
