odd man out
& Justify.
Scandium Titanium Gallium
Germanium.​

Answer 1

Answer: Gallium is the odds one!!

Step-by-step explanation:

Answer 2

There are two possible answers to this question:

(1st)

The odd one among the following is Germanium.

- The elements Scandium, Titanium and Gallium all are metals.

- While Germanium is a Metalloid (or Semi metal or Semiconductor).

- It shows properties intermediate of metals and non- metals.

- Hence, it is the odd one among the following given options.

- It is the most accurate answer with respect to chemical behaviour.

(2nd)

Based on the physical properties, the odd one is Gallium.

- Scandium, Titanium and Germanium are all solids at room temperature.

- They have very high melting point.

- But the metal Gallium has very low melting point and hence it is liquid at room temperature.

- So, with respect to physical state, the odd one is Gallium.
