The element aluminum forms a cation with the charge of +3. The symbol for this ion is Al³⁺, and the name is aluminum ion. The number of electrons in this ion 10.
<h3>What are ions?</h3>
Ions are formed when an atom gains or loses electrons.
Metals form positive ions by a loss of electrons whereas non-metals form negative ions by gaining electrons.
The aluminum ion is formed when aluminum loses three electrons to form Al³⁺ ion which has 10 electrons.
in conclusion, ions are formed by a gain or loss of electrons.

There are 6 electrons in the atom of a carbon.
The first atomic level will be occupied by 2 electrons while the second will be occupied by 4 electrons.
Based on this, the outer valence shell of carbon (which is L shell) will be occupied by 4 electrons.
1. No
2.No

Answer:
An atom cannot have 0.9 of a neutron.
Explanation:
Isotope of hydrogen is Protium, 11H, which has one proton, one electron and no neutron. Another isotope of hydrogen, deuterium has one proton, one electron and one neutron. There are no elements with 0.9 neutron. It is not possible for an element to have fraction of a neutron, the neutron is always a whole number.
Answer:
molar mass CO = 28.01 g/mol
3.45 x 10^2 x 28.01 =9.66 x 10^3 g
mass Zn = 2.45 x 10^-2 x 65.39 g/mol=1.60 g => 1.60 x 10^0
