How many protons and neutrons are in aluminum 27?
A quick looks in the periodic table will show that aluminium has an atomic number equal to 13 . This means that any atom that is an isotope of aluminium will have 13 protons in its nucleus.

- A quick looks in the periodic table will show that aluminium has an atomic number equal to 13 . This means that any atom that is an isotope of aluminium will have 13 protons in its nucleus.
- Just carbon and hydrogen. A classic hydrocarbon fuel. In the presence of sufficient oxygen, LPG burns to form water vapour and carbon dioxide, as well as heat. If not enough oxygen is present for complete combustion, incomplete combustion occurs with water, carbon monoxide, and carbon dioxide being produced.
So for the element of ALUMINUM, you already know that the atomic number tells you the number of electrons. That means there are 13 electrons in a aluminum atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and three in shell three.
- Aluminum compounds occur in all types of clay, but the ore that is most useful for producing pure aluminum is bauxite. Bauxite consists of 45-60% aluminum oxide, along with various impurities such as sand, iron, and other metals.
- Mild steel shows a ductile-brittle transition at around -60 °C. Results for aluminium show that it become slightly less ductile as the temperature is increased, and all the values for impact energy lie between the ductility of copper and the brittleness of acrylic.
- But today, the material is predominantly mined in Australia, Africa, South America and the Caribbean. The first step in the commercial production of aluminum is the separation of aluminum oxide from the iron oxide in bauxite.
Here, mass number is 27 and there are 14 neutrons hence protons=27-14=13. In a neutral atom, number of protons=number of electrons. Hence in this case the number of electrons in the neutral atom will be 13. Now, since the atom carries +3 charge hence it will have 13-3=10 electrons.
- Calcium-loses 2, Fluorine-gains 1, Aluminum-loses 3, Oxygen-gains 2.
How many electrons will each of these elements gain or lose in forming an ion: calcium, fluorine, aluminum, and oxygen? +1.
Identify the charge of the ion formed when a potassium atom loses one electron.
- CATIONS. Initially, the aluminum atom had a charge of +13 + (−13) = 0; in other words, its charge was neutral due to the equal numbers of protons and electrons. When it becomes an ion, it loses 3 electrons, leaving behind only 10. Now the charge is +13 + (−10) = +3.
- Remember a neutral atom has equal numbers of positive protons and negative electrons.) So there must be 18 electrons.
For Al3+ there are 13 protons since aluminum has an atomic number of 13, and there are 10 electrons.
