In order for it to be a cation, the maximum number of electrons it can have is one less than the number of protons. I don't know what "needed" means in this context, but hopefully that answers what you were trying to ask.
The least number of electrons needed in a shell is 2, as the first shell can hold a maximum of 2 electrons.
The Mg2 plus cation has 10 electrons.
The number of electrons is 10.
This describes an ionic compound with an 8:3 ratio of electrons to cations. The cation has a charge of +3, meaning it has lost 3 electrons. The total number of electrons in the compound is 80.
yes.they have the maximum number of electrons in their outer energy level?
The least number of electrons needed in a shell is 2, as the first shell can hold a maximum of 2 electrons.
The Mg2 plus cation has 10 electrons.
The number of electrons is 10.
the number of electrons lost when forming an ion and that the cation can form more than one cation.
A cation has a number of electrons lower than a neutral atom.
The atomic number of the cation is the same as the atomic number of the neutral atom.
An ion with missing electrons, and thus a positive charge, is a cation.
2 electrons is the maximum number for an single orbital.
This describes an ionic compound with an 8:3 ratio of electrons to cations. The cation has a charge of +3, meaning it has lost 3 electrons. The total number of electrons in the compound is 80.
2 electrons are found in the first electron shell.
The maximum number of electrons in a single d subshell is 10.
The element with 10 electrons when it forms a cation with a 1 plus charge is Neon (Ne). Neon has an atomic number of 10, which means it has 10 protons and 10 electrons. The cation is formed when an electron is removed from Neon, leaving it with 9 protons and 1 electron, giving it a 1+ charge. Neon's atomic number: 10 Neon's electrons when forming a cation: 10 Neon's protons when forming a cation: 9 Neon's charge when forming a cation: 1+
