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?
Stats for helium:Atomic number: 2Atomic mass: 4.002Protons: 2 (the same as the atomic number)Electrons: 2 (same as the number of protons)Neutrons: 2 (usually)Symbol: He
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
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.
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 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?
10 protons, 10 neutrons, 12 electrons
How many protons and neutrons in the fluorine?
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons. It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10. thus, fluorine has 9 protons and 10 electrons.
How many electrons and protons are present in Mg 2?
ans 12 atomic no. of Mg is 12 and in Mg2+ there is a lose of only 2 electrons so no. of protons shall be unchanged.
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.
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!
The Isotope neon-22 has 10 protons. How many electrons and neutrons does it have?
Protons an electrons are always the same so it would have 10 electrons and neutrons are the atomic mass minus the atomic number so it would be 12
What is the atomic number of an atom that has 10 neutrons 8 protons and 8 electrons?
It would be 8, and it is the element oxygen. The atomic number is simply the number of protons in the element.
How do you know how many electrons are in an atom?
Except for ions, the number of electrons in an atom are equal to the number of protons. The atomic number will tell you the number of protons, and consequently the number of electrons in an electrically neutral atom. In the case of an ion, adjust the number by the indicated charge; for example Na+1 will have 11 (the atomic number of Na) - 1 (since electrons have a negative charge, you subtract the charge) = 10 electrons.
