• Electronegativity is the ability of an atom to attract a shared pair of electrons in a covalent bond.
• It measures the ability of an atom to pull electrons towards itself.

Explanation

The charges of Proton, Electron, Neutron respectively are:

• Proton: Positive charge (+1)

• Neutron: Neutral charge (0)

Explanation

Fats are found in various food sources, including:

• Oil (such as olive oil, coconut oil, etc.)
• Butter
• Margarine
• Seeds (such as sunflower seeds, pumpkin seeds, etc.)

Explanation

• Radioactivity was discovered by Henri Becquerel, a French physicist, in 1896.
• He discovered this when he was studying uranium and noticed that it emitted radiation without an external source of energy.
  
• The term radioactivity was coined by Marie Curie, who, along with her husband, investigated this phenomenon.
• Rutherford, a British physicist, studied the properties of radioactive decay and named the particles alpha, beta and gamma.
