Question

Find the odd one out.
Beryllium, Magnesium, Calcium, Aluminium
With reason

Answer 1

Answer:

Beryllium

As all other are highly reactive metals

Answer 2

Answer:

Concept:
Different types of materials are all around us, including metals and nonmetals. Metals and nonmetals are two categories into which elements can be subdivided, and it is crucial to understand if a specific element is a metal or nonmetal.

Explanation:

Nonmetals like phosphorus and sulphur are insulators, whereas metals like copper and aluminum are good conductors of heat and electricity.

Given are Beryllium, Magnesium, Calcium, and Aluminum

The odd one is Aluminum. Because it is a metal and the remaining are nonmetals.

These are a few of the physical characteristics of metals.

• lustrous (shiny) in appearance
• A good conductor of heat and electricity is metal.
• High density and melting point
• Ductile that moulded
• Except for mercury, it is solid at ambient temperature.
• Opaque

The following is a list of several non-metals physical characteristics.

• inadequate heat and electricity conductors
• non-during metals
• Broken solids
• perhaps at ambient temperature, solids, liquids, or gases
• These lack sonority
• Transparent
