Which one of the following statements is correct?
a. an electron has a negative electrical charge.
b. an electron has a neutral electrical charge.
c. an electron is much larger than an atom.
d. an electron is located inside the nucleus of an atom.

Option (A) is the correct answer.

Explanation:

An atom consists of three sub atomic particles. These particles are protons, electrons and neutrons.

Protons have a positive charge. Whereas neutrons have no charge. On the other hand, electrons have a negative charge.

Thus, we can conclude that out of the given options, an electron has a negative electrical charge is the correct statement.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

lol for the pointsss
