aleksley [76]

Answer:

The answer to your question is below

Explanation:

Polyatomic ions are ions composed for more than 1 atom. There are polyanions and polycations.

Polyanions have a negative charge and polycations have a positive charge.

Examples

                      Polyanions                             Polycations

  acetate           CH₃COO⁻        ammonium      NH₄⁺¹                                    

  bromate          BrO₃⁻

  chlorate           ClO₃⁻

  hydroxide        OH⁻

  nitrate              NO₃⁻

  nitrite               NO₂⁻

  sulfate             SO₄⁻²

  phosphate      PO₄⁻³

  permanganate  MnO₄⁻

We write parentheses before or after a polyatomic ion to emphasize that the oxidation number of the atom which interacts with it affects all the atoms that form part of the polyatomic ion.

Which of the samples described below contains the FEWEST atoms? No calculation is needed to answer this question.
Monica [59]

Hello!

To do this, use the molar mass. This is how much a mole of an atom weighs. A mole is 6.02214076×10²³ atoms.

Molar masses of:

Se: 78.96 g/mol

Cu: 63.546 g/mol

Ba: 137.327 g/mol

Now, the element with the highest molar mass will have the fewest atoms. This is because the element weighs more, so therefore for the same amount of mass, there will be less of the element needed to reach that mass.

Therefore, 10g of Ba would have the fewest number of atoms.

Hope this helps!
