Which answer correctly ranks the atoms in terms of decreasing electronegativity (the highest electronegativity first)? which answer correctly ranks the atoms in terms of decreasing electronegativity (the highest electronegativity first)? c, h, o, n o, n, c, h n, o, c, h o, n, h, c n, o, h, c?

Answer 1

The correct answer to rank the atoms in terms of decreasing electronegativity (the highest electronegativity first) is n, O, C, H.

Step-by-step explanation:

The correct answer to rank the atoms in terms of decreasing electronegativity (the highest electronegativity first) is:

1. n, O, C, H
2. Explanation: Electronegativity generally increases from left to right across a period in the periodic table. Therefore, the atom with the highest electronegativity is oxygen (O). Among the given options, the one with oxygen first is option n, O, C, H.

Answer 2

O, N, C, H

Step-by-step explanation:

Electronegativity of an element is the property that combines the ability of its atom to lose or gain electrons. It measures the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.

On the periodic table, Electronegativity increases across the period but decreases down a group.

To solve the given problem, let us use thE Pauling's table of electronegativities to compare the electronegativities of the elements.

On the table:

C = 2.5

H = 2.1

O = 3.5

N = 3.0

In terms of decreasing electronegativities, the atoms are arranged as:

O N C H
