$\huge\pink{\mathcal{→ answer}}$

$\blue{\mathcal{(a)\:Liquid\;Metal}}$

≈≈> Exceptions include francium (Fr), caesium (Cs), rubidium (Rb), mercury (Hg) and gallium (Ga), which can be defined as liquid metals. This brings them additional advantages in comparison with the other metals; for example, they are fluid, stretchable and reformable at room temperature

$\blue{\mathcal{(b)\:Metalloid}}$

≈≈> Examples of metalloids include boron (B), silicon (Si), germenium (Ge), arsenic (As) and antimony (Sb). Their properties are in between those of metals and non metals.

$\blue{\mathcal{(c)\:Liquid \; Non-metals}}$

≈≈> Bromine is the only non-metal which exists in the liquid state at room temperature

$\blue{\mathcal{(d)\:Soft\;metal}}$

≈≈> Soft metals, such as indium, silver, gold, tin, lead, and related alloys, have been extensively investigated as surface engineering materials in the form of films or coatings.

$\blue{\mathcal{(d)\:Non-metal\;that \;conducts\;heat}}$

≈≈> Graphite is a non-metal and it is the only non-metal that can conduct electricity. You can find non-metals on the right side of the periodic table and graphite is the only non-metal that is a good conductor of electricity.

Answer 2

Explanation:

(a) Mercury is the only metal that is liquid at normal temperatures.

(b) Germanium, arsenic and antimony are classified as metalloids since they have some properties of metals and some properties of non metals.

(c) Bromine is the only non-metal that is in liquid at room temperature.

(d) Sodium and potassium are soft metals.

(e) Graphite is the non metal that is both a good conductor of heat and electricity.
