Answer: Option (a) is the correct answer.
Explanation:
Non-metals are the species which in order to complete their octet readily gain an electron.
For example, fluorine is a non-metal with atomic number 9 and its electronic distribution is 2, 7.
Hence, to attain stability it readily accepts an electron from a donor atom.
Some characteristics of non-metals are as follows.
Non-metals do not conduct electricity.
Non-metals are brittle in nature and they have a rough surface.
Non-metals are not malleable or ductile.
Thus, we can conclude that non-metals do not conduct electricity is a characteristic of non-metals.
Ionic bonds are made up of a metal and a nonmetal elements while covalent bonds are are made up of two metal. So, you can just look at the periodic table and identify which compounds have two metals and which have one metal and one nonmetal. Also, those compounds with high electronegativity difference are very likely to be ionic while the opposite is covalent. HOWEVER, some compounds can be both covalent and ionic. For instance, if HCI gas is at higher temperatures, then it is ionic while it would be covalent at room temp.

Answer:
Chiral:
3-Methyl-2-butanol
Achiral:
1-Pentanol
3-Pentanol
3-Methyl-1-butanol
Explanation:
Only the molecule that bears a carbon atom surrounded by 4 different groups can be said to be Chiral, the other molecules don't satisfy this property.
There rlly isn’t noooo number so what do you expect of course it would be zero. 0£
Lines in one spectral series can overlap lines in another is rydberg
In several chemical elements, the Rydberg formula is used to compute the wavelengths of spectral lines.
<h3>
What causes lines in a line spectrum?</h3>
A spectral line is similar to a fingerprint in that it can be used to identify the atoms, elements, or molecules in a star, galaxy, or cloud of interstellar gas. When we use a prism to split incoming light from a heavenly source, we often observe a rainbow of colours crossed by definite lines. It's worth noting that spectral lines can appear in other parts of the electromagnetic spectrum, however we can't use a prism to assist us identify them.
Emission lines are distinct coloured lines that appear on a black backdrop and correspond to certain wavelengths of light emitted by an item.
Absorption lines are visible as black bars.
