Which characteristic is needed for an atom to have an expanded octet? salt while in a covalent bond , atoms have the same electronegativity values al one another, that is why electrons ase shared between atoms . h. If no man is tall, then some woman is not tall. :). If the reaction was treated with a catalyst, which would most likely represent the amount of energy needed to start a reaction? Two electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms. What does the 4 mean in the formula 4Na2SO3? Atoms can also make chemical bonds by sharing electrons equally between each other. 1 calcium, 2 oxygen, and 2 hydrogen They are metals. AP.BIO: SYI1 (EU) , SYI1.B (LO) , SYI1.B.1 (EK) Google Classroom. The bond energies in Table 8.2 "Bond Energies of Covalent Bonds" are average values; the exact value of the covalent bond energy will vary slightly among molecules with these bonds but should be close to these values. To achieve stability, carbon must find four more electrons to fill its outer shell, giving a total of eight and satisfying the octet rule. When placed at room temperature, the substance quickly turned into a liquid.
