Answer from: Wolfiid

= -1

Explanation:

Chlorine belongs to the halogen group in the periodic table. It has an atomic number of 17, which indicates the number of protons and electrons in a neutral atom of chlorine is 17.Therefore; with an atomic number of 17, its electronic configuration will be 2:8:7. Thus; to attain a stable configuration chlorine requires to gain one electron, by so doing it becomes a negatively charged ion with a charge of -1.

Answer from: AutumnJoy12

Explanation:

When a neutral atom tends to gain an electron then it acquires a negative charge. Hence, an anion is formed.

For example, atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.

So, in order to attain stability it tends to gain one electron from a donor atom. Therefore, a chlorine ion is formed as $Cl^{-1}$ .

Since, it gains only one electron that is why, -1 charge occurs. Whereas if an atom gains two electrons then it acquires a -2 charge and so on.

Thus, we can conclude that chlorine (Cl) has an atomic number of 17. It often forms an ion by gaining 1 electron. Its charge be -1.

Answer from: Quest

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.

Answer from: Quest

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.
