The Electronegativity Values of Some Elements
Which element attracts electrons most strongly in chemical bonds?
Consider the positions of carbon, nitrogen, potassium, and calcium on the periodic table.
Atoms of which element attract electrons most strongly in chemical bonds?
A) carbon (C)
B) calcium (Ca)
C) nitrogen (N)
D) potassium (K)
Answer is: nitrogen (N) attract electrons most strongly in chemical bonds.
Electronegativity (λ) is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.
λ(C) = 2.55; electronegativity of carbon.
λ(Ca) = 1.00; electronegativity of calcium.
λ(N) = 3.05; electronegativity of nitrogen.
λ(K) = 0.82; electronegativity of potassium.
The higher the electronegativity, the more the element attracts electrons.
