The mass number of the atom is 21, the atomic number is 9, and the element is Fluorine. There are 9 protons, 9 electrons, 12 neutrons, and the elemental symbol is F.

<h3>Properties of an atom</h3>

For every atom:

  • Protons and neutrons are located in the nucleus and the addition of both equals the mass number of atoms.
  • Electrons are located outside the nucleus, in orbitals.
  • Neutral atoms have the same number of electrons and protons

In the diagram:

Number of electrons = 9

Number of protons = 9

Number of neutrons = 12

Mass number = 12 + 9

                      = 21

Atomic number = number of protons

                         = 9

Element with atomic number 9 = Fluorine

Symbol of the element = F

The unknown ionic compound gave a red flame test, NR with ammonium carbonate, and a red/orange halide test. What is the unknown
harkovskaia [24]

Answer:

This question is incomplete, however, the unknown compound can be inferred to be "Lithium Bromide"

Explanation:

The unknown compound firstly is said to be an ionic compound. An ionic/electrovalent compound is a compound in which it's constituent ions transfer/receive electron(s). They are mostly made of group 1 and group 7 elements. Examples include NaCl, NaF, LiF and KCl.

Also, the ion (metallic ion) that produces a red flame test colour in a flame test is the <u>Lithium ion (Li⁺).</u> Also, when dissolved in water or hexane, the only halogen that produces a red/orange colour is bromine. Hence, the unknown ionic compound can be inferred to be Lithium Bromide.

what is the difference between the number of electrons in an atom of selenium, Se and the number of electrons in an atom of alum
ELEN [110]

Answer:

Well, electrons can be converted into a atomic number so if SE atomic number is 34 that means it has 34 electrons. AI has a atomic number of 13 meaning it has 13 electrons. So the difference is that SE has more electrons then AI.

What happen when molten zinc bromide is electrolysised
worty [1.4K]

Answer:

Molten lead bromide, PbBr 2(l), is an electrolyte. During electrolysis: Pb 2+ ions gain electrons at the cathode and become Pb atoms. Br - ions lose electrons at the anode and become Br atoms, which pair up to form Br 2 molecules.
