Answer:
Explanation:
Thermal stability is the tendency to not break down when exposed to heat. A more negative enthalpy of formation will correlate with more stable products. Therefore, the more negative the enthalpy of formation is for a substance, the greater its thermal stability.

Answer:
Explanation:
Given elements:
Sodium
Fluorine
The ion Na⁺ is made up of 10 electrons, its electronic configuration is:
1s² 2s² 2p⁶
Ion F⁻ is made up of 10 electrons, its electronic configuration is:
1s² 2s² 2p⁶
These ions do not form +2 because they cannot attain stability by losing or gaining two electrons.
Sodium atom is made up of one valence electron. If it loses one electron, it will be isoelectronic with Neon.
Fluorine has 7 valence electrons, to attain stability, it must gain one electron to form an octet. This way it will be isoelectronic with Neon.
Losing or gaining two electrons will not make the elements attain stability.

Answer:
nothing haha because I don't know what is the answer
Answer:
Li-F
Explanation:
Hydroxide is a negative ion, which can form ionic bonds with metals, but the bond in hydrogen and oxygen in hydroxide (OH-) is not ionic. It is covalent in nature.
C-C is clearly a covalent bond.
Li-F is an ionic bond.
Bond between H and Cl in H-Cl is covalent in nature. Because of the size difference hydrogen can not act as a cation. So it rather dissociates.
