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.

Which reason best explains why metals are ductile instead of brittle?

MaRussiya [10]

Answer: -

Metals are ductile instead of brittle because they have flexible bonds.

Explanation: -

Metals have a property called ductility.

It is the ability of a metal to be drawn into wires.

Metals due to greater bond flexibility are more ductile.

The most ductile metal known to man is Gold. Metallic wires find many applications in modern machinery particularly.

Usually ductility and malleability go together.

Question 3

harina [27]

Answer: 0.118M

Explanation:

The formula for molarity is: $M=\frac{mol solute}{L solution}$

First, we need to find the number of moles of NaCl.

$2.70gNaCl*\frac{1molNaCl}{58.44gNaCl} =0.05molNaCl$

Next, we must convert millimeters to liters. We can do that by dividing the number of mL by 1000.

$\frac{425mL}{1000} =0.425L$

Now we have our needed data! All we need to do now is plug in our data to the molarity formula.

$M=\frac{0.05mol}{0.425L} =0.118M$

I hope this helps! Pls mark brainliest!! :)
