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? (5 points)
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.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

1. they vary with a higher number because boiling is way hotter than melting

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
