How many electrons will Aluminum lose when it forms an ion?
three electrons
An aluminum atom will lose up to three electrons when it forms an ion, creating the Al+, AL2+ or Al3+ cation. Atoms are most stable when they have a…
Does aluminum gain or lose electrons to become an ion?
Aluminum is a metal that will always lose three electrons. The halogens all have seven valence electrons. Each one of these elements wants to gain one electron to achieve an octet. Metals will always lose electrons to form cations.
What charge will an ion of selenium take?
To summarize: Selenate has a charge of (-2), with an Se ion of charge +6. Selenite has a charge of (-2), with an Se ion of charge +4.

Is oxygen a cation or anion?
Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).
What charge does aluminum have when it becomes an ion?
The charge of an aluminum ion is typically 3+. This is because the element’s atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons.
Is aluminium an atom or ion?
Aluminium(3+) is an aluminium cation that has a charge of +3. It is an aluminium cation, a monoatomic trication and a monoatomic aluminium.
Does oxygen gain or lose electrons to form an ion?
The charge on an ion is equal to the difference in the number of electrons and that of protons it contains- in other words, the number of electrons its parent atom has gained or lost. An electrically-neutral oxygen atom gains two electrons to form an oxygen ion with two negative charges.
What does it mean if an ion has a 2+ charge?
If an ion has a 2+ charge then it must have lost electrons to form the cation. If the ion has 18 electrons and the atom lost 2 to form the ion, then the neutral atom contained 20 electrons. Since it was neutral, it must also have had 20 protons. Therefore the element is calcium.

How many electrons are lost in a selenium atom?
1. loss of 2 electrons. 2. gain of 1 electron. 3. loss of 1 electron. 4. loss of 7 electrons. 5. gain of 2 electrons. Help please and tell me how you got the answer.
Which is the most stable ion of selenium?
A selenium atom (Se) would form its most stable ion by the 1. loss of 2 electrons. 2. gain of 1 electron.
How many electrons will be gain or lose when it forms an ion?
How many electrons will be gain or lose when it forms an ion? All Group 1 atoms can lose one electron to form positively charged ions. For example, potassium atoms do this to form ions with the same electron configuration as the noble gas argon. Group 2 atoms lose two electrons to form positively charged ions.
How many electrons does sulfur gain or lose?
Sulfur has 16 electrons. To be isoelectronic with argon, which has 18 electrons, sulfur must gain two electrons. Therefore sulfur will form a 2 – ion, becoming S 2–. Is Iodine a cation or anion?
