The difference between Al and Al+3 is that the ion has lost 3 electrons, therefore it has 3 more protons than electrons, hence granting it a charge of +3.
The number of protons in each atom or ion of aluminum, irrespective of its chemical structure, is always 13, which is the atomic number of aluminum.
The stable ion of aluminum is Al 3+, which means it has three fewer electrons. The aluminum atom has shed its outer shell of 3s2 3p1 and has an electron configuration equal to that of Neon, or 1s2 2s2 2p6.
Lithium has three protons in the nucleus
Lithium has three protons and three electrons. The number of electrons always equals the number of protons. Lithium has two isotopes, one with three neutrons and one with four neutrons.
The three constituents that make an atom are protons, neutrons, and electrons.
Aluminum ions are positive, and have three neutrons in it.
Ions of an element are formed when electrons are added or removed. When protons are added or removed, the element itself is different. Aluminium can form 3+ ion by losing three electrons. Besides, if it was possible to add three protons to aluminium, the species formed will be sulphur atom and not aluminium atom.
All atoms of aluminum (aluminium) have 13 protons. Neutral atoms will also have 13 electrons.
The stable ion of aluminum is Al 3+, which means it has three fewer electrons. The aluminum atom has shed its outer shell of 3s2 3p1 and has an electron configuration equal to that of Neon, or 1s2 2s2 2p6.
It is the lithium metal. It could be a isotope of Li.
Lithium has three protons in the nucleus
When aluminum and bromine react, three bromine atoms combine with each aluminum atom.
Lithium has three protons and three electrons. The number of electrons always equals the number of protons. Lithium has two isotopes, one with three neutrons and one with four neutrons.
The number of electrons is equal to the number of protons which determines it's atomic number. Therefore, the element with 3 electrons is the one with 3 protons which has an atomic number of three which is Lithium (symbol - Li, amu - 6.941)
The atomic number of any element depends on the number of protons it has in its nucleus. Aluminium has 13 protons hence making the atomic number of aluminum 13.
The three constituents that make an atom are protons, neutrons, and electrons.
Lithium has three protons because elements always have the same number of protons.
The numbers preceding the element or compound in a chemical equation are coefficients.For example, 2Mg + 3Al means that there are two magnesium atoms (or two moles of magnesium) and three aluminum atoms (or three moles of aluminum). Most importantly, the 2 and 3 reflect the ratio of magnesium to aluminum in the equation.
