Pls ans

I will make u Brainliest​

Answer 1

Answer:

K, Na, Al, s are in increasing order of electronegativity

Answer 2

Answer:

increasing order :S ,K,Na and Al

Explanation:

Electronegativity is nothing but the ability to attract shared pair of electrons.

1.Always the electronegativity is higher for the non metals than metals ,so S(sulphur) is non metal it is having highest electronegativity.

2.electronegativity is depending on atomic size which is having lowest atomic size having high electronegativity.

so atomic size order is :K>Na>Al.

I hope u get it .
