Al3+ ion: because Aluminium is (atom)number 13 in the periodic system, so it has 13 protons.
If 10 of them have counter-parting electrons then 3 positive proton charges are left uncompensated (by missing 3 electrons from the outer 'shell' or 3 valency electrons)
So the ion charge is 3+.

What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
What is the atominc number the atomic mass the number of protons neutrons and electrons in an atom of neon?

How many neutrons protons and electrons in fluorine?
The atomic number of fluorine is 9. So it has 9 protons and 9 electrons. Number of neutrons depends on the isotope. Number of neutrons = Mass number - Atomic number F-19 has 10 neutrons
How many protons neutrons electrons in atom of fluorine?
An atom of Fluorine has the atomic number 9 and the mass number 19 (rounded up). This means it has 9 electrons, 9 protons and (19-9) 10 neutrons. The proton and electron count are taken from the atomic number. The mass number - the atomic number gives the number of neutrons.
What is the total number of neutrons in the nucleus of a neutral atom that has 19 electrons and da mass number of 39?
The mass number is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus.Thus add the number of neutrons (20) to the atomic number (which is a count of the number of protons) 19 to give a mass number of 39.
What is the number of protons of neon?
The number of electrons that a nucleus has is equal to the elements' atomic number, found on the periodic table. In the instance of neon (Ne), its atomic number is 10; therefore, it has 10 protons.
How many protons neutrons and electrons would an atom of neon have?
- The atomic symbol is only an abridged form of the name of a chemical element. - The chemical symbol of neon is Ne; the atomic number is 10. - The atomic number is equal to the number of protons and electrons. - Number of neutrons = Atomic mass of an isotope - Atomic number
How protons and electrons in neon?
In an atom, 10 protons and 10 electrons. (# of protons = atomic number) =)
How many protons neutrons and electrons are in a neutral atom of neon if its atomic number is 10 and its mass number is 22?
A neutral atom of neon with atomic number 10 has 10 protons and 10 electrons. The mass number of 22 indicates the total number of protons and neutrons combined. Since the atomic number is 10, the number of neutrons is 22 - 10 = 12.
How many electrons and protons are present in Mg 2?
There are 12 protons and 10 electrons present in Mg2. This is because magnesium (Mg) has an atomic number of 12, meaning it has 12 protons. The 2- charge indicates that the atom has gained 2 electrons, resulting in 10 electrons.
If an atom with an atomic number of 10 and a mass number of 24 would have?
This atom would have 10 protons, 10 electrons, and 14 neutrons. The atomic number (10) represents the number of protons, the mass number (24) is the sum of protons and neutrons, and since atoms are electrically neutral, it would have the same number of electrons as protons.
How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence electrons?
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
How many protons and electrons and neutrons does beryllium-10 have?
Beryllium-10 has 4 protons and 4 electrons. Since the atomic number of beryllium is 4, this is how many protons and electrons it has. Beryllium-10 is an isotope, which means it has 6 neutrons, as the total mass number of beryllium-10 is 10.
Does fluorine contain 10 electrons?
it has 9 electrons atomic number= number of protrons and electrons and atomic mass-atomic number=neutrons
What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
How do you find the number of electrons in element?
The Atomic Number of the element is equal to the number of electrons. Also, the number of protons is also equal to the Atomic number; so the number of protons and electrons in any given element is the same!
How many electrons in atom with atomic number of 9 and atomic mass of 19 and is electrically neutral?
Since the atom is electrically neutral, the number of electrons must be the same as the number of protons in the atom, which is the definition of atomic number. Therefore, there are 9 electrons.
