Answer:
As the difference in electronegativity between two atoms decreases, the tendency for the formation of covalent bonds "increases"
Explanation:
Electronegativity being a chemical property which tells us about the tendency about the atom in order to fascinate the shared pair of the electron towards itself. It is being pretentious by atomic number and the distance as well, by the help of which the valence electrons resides from the charged nucleus. In the scale Pauling scale is used. Being the most electronegative element fluorine is counted. The more the electronegativity, the more electrons will fascinate towards itself.
Answer:
During a phase change no chemical bonds are broken. Atoms are not rearranged because a phase change is a physical change rather then a chemical change. However, intermolecular forces are almost entirely removed from the liquid since the intermolecular forces are what cause the liquid to be a liquid.
Explanation:the nature of the intermolecular forces (IMF) will not change when the state changes from solid to liquid, however, the number of IMF changes.
Answer:
Option-A is the correct answer
Explanation:
Lithium belong to group 1 metals. Hence, it can loose one electron to form lithium ion i.e. Li⁺¹ or Li⁺
While, Nitrogen is non-metal and hence has the ability to gain the electron lost by lithium metal. Furthermore, Nitrogen can gain maximum 3 electrons to acheive noble gas configuration. Hence, three Li atoms will loose their electrons and Nitrogen will gain those three electrons to form nitride ion i.e. N³⁻.
Compound is X3Y2.
Hope this helps you!
