Valence electrons are the total amount of electrons on the outermost shell of an atom. Meaning if the last shell has two, the valence electrons are two. But a complete valence shell would hold eight.

Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.

it needs six more electrons to have a full outer valence shell.
If magnesium (Mg) has a full valence shell, it would have a 2+ charge. This is because magnesium has 2 valence electrons and would need to lose these electrons to achieve a full valence shell, resulting in a 2+ charge.
3 valence electrons. As the atomic number of boron is 5, it would have 2 electrons in the first shell and 3 valence electrons in the second shell.

Nitrogen needs 3 more electrons to have a complete valence shell of 8 electrons. Nitrogen has 5 electrons in its valence shell, and a complete valence shell for nitrogen would have 8 electrons to achieve stability.
The valence shell is the outter most shell that contains the most electrons. To find out how many valences there are you would mulitply the electrons. C3H8= (6)3 + (1)8=26 the outer valence shell will be 20.

Eight valence electrons would complete the out shell. If the outer shell was complete it would still be called the same thing, however the charges would be different.
200because the pizza guy came to my houseand i asked him the same question and he told me 200....or maybe that was the bill??
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
Aluminum would lose 3 electrons to become like argon. Argon has a full valence shell with 8 electrons, so aluminum, with 3 valence electrons, would need to lose these electrons to achieve a full valence shell configuration similar to argon.
