They all have the same number of protons (12).
The number of protons (the atomic number) is the same for all atoms and ions of Na.
However, atoms and ions have different numbers of electrons.
An <em>Na atom</em> has 11 electrons, but an <em>Na^(+) ion</em> has only 10 electrons.
Answer:
3 RbOH + H₃PO₄ → Rb₃PO₄ + 3 H₂O
Explanation:
Let's consider the double-replacement reaction between rubidium hydroxide and phosphoric acid to form rubidium phosphate and water. The cation rubidium replaces the cation hydrogen and the anion hydroxyl replaces the anion phosphate. The balanced chemical reaction is:
3 RbOH + H₃PO₄ → Rb₃PO₄ + 3 H₂O
Answer:
A) protons
Explanation:
Protons are what give atoms their elements. If one atom has a differing number of protons from another atom, they will never be the same element.
Answer:
Can I get my 50 points now?
Explanation:
The helium is formed during the natural radioactive decay of elements such as uranium and thorium. These heavy elements were formed before the earth but they are not stable and very slowly, they decay. One mode of decay for uranium is to emit an alpha-particle.
