What is the symbol for an atom with 23 protons 28 neutrons and 18 electrons?

Answer 1

You will need a Periodic Table to answer this question. The atom has 23 protons, which is its atomic number. Look up the periodic table and get the element symbol for the atom with atomic number = 23. It is V (vanadium). The atom is not a neutral atom, since it has two electrons less (21) than the protons (23). So the atom V has lost 2 electrons which means it has 2+ charge. The answer for question is V2+.

Answer 2

No neutral atom can have the numbers given, because the number of electrons is not equal to the number of protons. An atom or ion of vanadium, chemical symbol V, has 23 protons, and if it also contains 28 neutrons must have the mass number of 23 + 28 = 51. This is the most common isotope of vanadium.

In the compound potassium vanadate with formula KVO3, vanadium is generally considered to have a formal charge of +5. corresponding to the given number of protons and electrons. Therefore, the letter V in KVO3 could plausibly be said to satisfy all of the conditions of the problem.

Answer 3

This is "isotope notation" and it basically switched. Protons goes on bottom left and neutrons takes the position of where the atomic number would be. So in this case

29

V

23

Answer 4

If it has 28 protons, then it is nickel. The isotopic symbol is 59Ni (one could also add the atomic number {28} as a subscript directly below the mass number {59})

Added:

59Ni is a not naturally occurring radio isotope with a half-life of 76,000 years. It is rather rare.

Answer 5

The atom has 23 protons (+), 20 electrons (-), and 28 neutrons (no charge). Since it has 3 more protons than it does electons then it will have an overall charge of +3. So the important feature would be that it is a Cation with a +3 charge.

Answer 6

Vandium - the number of protons/electrons is also the atomic number. Vanadium's atomic number is 23.

Answer 7

This is the cation of potassium: K+.
