8 - called valence electrons. it doesn't matter what energy level or orbital shape. a "happy atom" has 8 valence electrons
The electrons in the outermost level are known as the valence electrons.
It depends on the atom. List what element the atom is from.
Oh, dude, stable atoms typically have 8 valence electrons because they want to be all balanced and happy. It's like they're throwing a party and they need 8 cool electrons to join in on the fun. So yeah, 8 valence electrons is the magic number for stable atoms.
It would have a negative charge. It would be a negative ion with a 2+ charge.Remember: when an atom gains electrons they become NEGATIVE.when an atom loses electrons they become POSITIVE.
A neutral atom of fluorine contains 7 valence electrons.
A neutral atom of oxygen would have 6 valence electrons.
A neutral atom of aluminum has 3 valence electrons.
A neutral atom of silicon will have 4 valence electrons. The amount of valence electrons that a neutral atom will have can be found by the atoms group number in the periodic table.
A neutral atom can have a maximum of 8 valence electrons, following the octet rule. This applies to elements in the second period and beyond on the periodic table. Exceptions include hydrogen and helium, which can have a maximum of 2 valence electrons.
Two valence electrons
A hydrogen atom has 1 valence electron.
A neutral Si atom has 3 valence electrons, which reside in the 3rd energy level valence shell. Therefore, there are 3 valence orbitals in a neutral Si atom.
Aluminum has 3 valence electrons.
That neutral silicon atom has four electrons in its valence shell.
Hydrogen has 1 valence electron. Bromine has 7 valence electrons. When hydrogen and bromine react, the bromine atom 'steals' the hydrogen atom's only electron. The hydrogen atom then has no electrons and the bromine atom has 8 valence electrons. The two atoms are now ions because their number of protons does not equal their number of electrons. The bromine atom is now a bromide anion and the hydrogen atom is now a hydrogen cation (a proton). The two ions remain together, ionicly bonded and together are called hydrogen bromide.
A silicon atom has 4 valence electrons and each hydrogen atom has one valence electron, for a total of 8.
