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+.
The atomic number is equal to the number of protons in an atom. In this case, if there are 13 protons, the atomic number is 13. The number of electrons does not affect the atomic number of an atom.

What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
The atomic number is 9 (19 - 10 = 9) and the symbol for the element is F.
What is the atominc number the atomic mass the number of protons neutrons and electrons in an atom of neon?
Neon has an atomic number of 10 and an atomic mass of about 20. The number of protons in a neon atom is 10, which also corresponds to the number of electrons since neon is electrically neutral. As a noble gas, neon typically has 10 neutrons in its nucleus.
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 (A) is equal to the total number of protons and neutrons in the nucleus. Since the atom is neutral, the number of protons is equal to the number of electrons. Given that there are 19 electrons, this means there are also 19 protons. Therefore, the total number of neutrons can be calculated as A - number of protons, which is 39 - 19 = 20 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?
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?
No, fluorine contains 9 electrons. It has an atomic number of 9, which corresponds to the number of protons and electrons in a neutral fluorine atom.
What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
The atomic number is 9 (19 - 10 = 9) and the symbol for the element is F.
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?
A neutral atom will have an equal number of protons and electrons. With an atomic number of 9, the atom has 9 protons. The atomic mass of 19 indicates that there are 10 neutrons. Therefore, there will be 9 electrons in the atom.
