Answer : An ionic bond is formed when <u>one atom transfers an electron to another atom.</u>
Ionic bond is formed when one or more electrons from the valence shell of an atom (electropositive metal ) are completely transferred to the valence shell of another atom (electronegative non-metal).
Ionic bonds form when one atom gives up one or more electrons to another atom. It is the complete transfer of valence electron(s) between oppositely charged atoms
For example NaCl (sodium chloride ) is an ionic bond, in which valence electron from Na gets completely transferred to the valence shell of Cl and ionic bond is formed between opposite ions that is Na (positive) and Cl (negative).
Note : Ionic bond is formed between metal (electropositive element) and non-metal(electronegative element).
Answer: Energy is absorbed, and kinetic energy increases
Explanation: Boiling is the phenomenon in which liquid is converted to gaseous state.
Thus in order to break the inter molecular forces of attraction present in a liquid, energy is required and thus the process is endothermic in nature.
As the molecules absorb energy, the kinetic energy of the molecules increases and they start moving faster and more randomly and convert into gaseous state.
<span>The answer is - a. Alkali Metal.
</span>They react violently with water to form alkaline solutions. This is because they all have 1 electron in their outer shell and losing 1 electron allows them to have full outer shells, and achieve stability.

A line graph is a graph that shows data connected by line segments.
Answer:
B. alanine aminotransferase.
Explanation:
Ketogenic amino acid contain low carbohydrate and have the keto acid group present in them. Examples of ketogenic amino acid include alanine, cysteine, glycine, serine, and threonine. These amino acids are usually converted to pyruvate.
Alanine aminotransferase helps by catalyzing the transfer of an amino group from alanine to alpha-ketoglutarate in the alanine cycle to form pyruvate and glutamate.
