Is Aluminium a cation or anion?
List of Ions in the CCCBDB

|---|---|---|
| Al- | Aluminum atom anion | -1 |
| Al+ | Aluminum atom cation | 1 |
| Sc+ | Scandium cation | 1 |

What is the charge of a cation group of answer choices?
A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
Which is not a cation?
Sulfate is an anion, not a cation.
Why is it called a cation?
An ion is a particle that has an electrical charge. When an ion’s charge is negative, it’s more specifically called an anion, and when it’s positive, you can use the term cation. The Greek source is kation, which means “going down.”
Why is an atom electrically neutral?
Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.
What is the octet rule and which elements obey the octet rule?
The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons and thus the electron configuration of a noble gas. An exception to an octet of electrons is in the case of the first noble gas, helium, which only has two valence electrons.
Why do only valence electrons involved in bond formation?
The nucleus and the electrons in the inner shell remain unaffected when atoms come close together. The electrons in outermost shell of an atom get affected. Thus electrons in valence shell are responsible for the formation of bond between atoms.
What is octet rule explain with example?
The octet rule dictates that atoms are most stable when their valence shells are filled with eight electrons. The octet rule is only applicable to the main group elements. The molecules of the halogens, oxygen, nitrogen, and carbon are known to obey the octet rule.
How is the octet rule used?
The octet rule can be used to explain the number of covalent bonds an atom forms. This number normally equals the number of electrons that atom needs to have a total of eight electrons (an octet) in its outer shell. For example, the halogens (Group VIIA), all have seven valence electrons.
Is Phosphorus an exception to the octet rule?
Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet. Phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom.
