The compound nitrogen have most positive oxidation state is NO₂. The correct option is b.

<h3>What is oxidation state?</h3>

The total number of electrons gained or lost by an atom in order to form a chemical bond with another atom.

The charge on an ion is equal to the sum of the oxidation states of all the atoms in the ion. A substance's more electronegative elements are given a negative oxidation state.

A positive oxidation state is assigned to the less electronegative element.

Thus, the correct option is b, NO₂.

14. A cinder cone is the simplest type of volcano.<br> a. True<br> b. False
dusya [7]

Answer:

True

Explanation:

They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone, making them the simplest out there

For an atom’s electrons, how many energy sublevels are present in the principal energy level n = 4?
defon
"n" represents principal energy level or principal quantum number. Principal energy levels are then subdivided into sublevels. The level of principal energy level is always equal to number of sublevels. Therefore if <span>principal energy level</span> = 4, then there are also 4 sublevels present, namely: 4s, 4p, 4d and 4f sublevels.

Which of the following best describes isotopes?
LenKa [72]

Answer: An element with the same number of protons, but a different number of neutrons

Explanation:

The # of protons in an atom is what determines what atom it is (hydrogen has 1 proton, helium has 2 protons, etc ...). You cannot change the number of protons in an atom without changing what element the atom is.

The number of electrons in atoms varies greatly because electrons are constantly gained, lost, and shared during chemical reactions.

An isotope is a variation of the same element (so they must have the same # of protons) that have different masses (and therefore a different number of neutrons).

The answer is the fourth choice, "An element with the same number of protons, but a different number of neutrons"
