When the electron cloud of a molecule is easily distorted, the molecule has a high . polarity b. polarizability c. dipole moment d. van der waals radius

Option (b) is the correct answer.

Explanation:

Polarity is defined as the development of partial charges on the atoms of a molecule.

Whereas polarizability is defined as the ability or measure of how readily an electron cloud is able to get distorted. More is the polarizability more will be the electron is distorted in nature.

A dipole moment is defined as the measurement of the separation of two opposite electrical charges.

Thus, we can conclude that when the electron cloud of a molecule is easily distorted, the molecule has a high polarizability.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

personal, she chose to do it.
