How do I get a full outer shell?
Atoms will try to gain or lose electrons in order to get a full valence (outer) shell. This is because an atom with a full valence shell is more stable. Atoms in the same group have similar properties because they have the same number of valence electrons.
How does oxygen get a full outer shell?
Oxygen needs two electrons to fill its outermost electron shell. Hydrogen has one electron to play with. Therefore, an oxygen atom needs two hydrogens to bond to in order to complete its shell.
Does carbon have a full outer shell?
Carbon ( Cstart text, C, end text), as a group 14 element, has four electrons in its outer shell. Carbon typically shares electrons to achieve a complete valence shell, forming bonds with multiple other atoms.
How does carbon complete its outer shell?
Carbon forms covalent bonds with atoms of carbon or other elements. Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons.
How many electrons can be held in each shell?
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
What are the rings around an atom called?
The rings, also known as electron shells, can hold a variable amount of electrons depending on its shell number. For example, the first shell can hold only two electrons. If the atom has more than two electrons, then that atom must have more than one ring.
How do electron orbitals work?
Electrons fill low energy orbitals (closer to the nucleus) before they fill higher energy ones. Where there is a choice between orbitals of equal energy, they fill the orbitals singly as far as possible. This filling of orbitals singly where possible is known as Hund’s rule.
