explain how a metal with one valence electron compares with a metal with more than one valence electron
slamgirl [31]

Explanation:

A metal with one valence electron is highly reactive compared to those with more than one electron.

Atoms including those of metals reacts in order attain a stable electronic configuration just like those of noble gases.

An atom with one valence electron have just one electron in its valence shell.

  • Metals generally have large sizes.
  • when the electron in this shell is lost, the metal atom can then attain stability.
  • therefore, such atom will quickly want to combine with any other willing to accept the electron so that they can be stable.
  • Those with more than one electron will find it difficult to lose them.
  • It requires huge energy to remove such electrons compared to the ones with only one valence electron.

HNO3 + H2O → H3O^+ + NO3<br> which ones are acids and which ones are bases
nlexa [21]

Answer:

  • HNO₃ and  H₃O⁺ are acids
  • H₂O and  NO₃⁻ are bases

Explanation:

The chemical equation is:

  • HNO₃ + H₂O → H₃O⁺ + NO₃⁻

There are several definitions of acid and bases: Arrhenius', Bronsted-Lowry's and Lewis'.

Bronsted-Lowry model defines and <em>acid</em> as a donor of protons, H⁺.

In the given equation HNO₃ is such substance: it releases an donates its hdyrogen to form the H₃O⁺ ion.

On the other hand, a <em>base</em> is a substance that accepts protons.

In the reaction shown, H₂O accepts the proton from HNO₃ to form H₃O⁺.

Thus, H₂O is a base.

In turn, on the reactant sides the substances can be classified as acids or bases.

H₃O⁺ contain an hydrogen that can be donated and form H₂O; thus, it is an acid (the conjugated acid), and NO₃⁻ can accept a proton to form HNO₃; thus it is a base (the conjugated base).
