Question

Which atom is likely to have a higher electronegativity?

• A. Non-metal oxygen, atomic number 8
• B. Metal beryllium, atomic number 4
• C. Non-metal selenium, atomic number 34
• D. Metal lead, atomic number 82
• E. Metal magnesium, atomic number 12

Answer 1

The correct option is A Non-metal oxygen, atomic number 8

Non-metal oxygen, atomic number 8
Electronegativity : This is the tendency of an element to attract the shared pair of electrons between two atoms.
Metals have lesser electronegativity, as these have electropositivity.
Electronegativity increases along the period, left to right.
Electronegativity decreases down the group.
