How does the outer shells of two atoms that are covalently bonded?
Wiki User
∙ 14y ago
In a covalently bonded molecule, atoms are bonded by the sharing of their electrons. When Oxygen combines with two Hydrogen, H2O is formed by two covalent bonds. Oxygen, which has 6 outer electrons, needs to gain two electrons to form a completely stable octet of electrons. Each of the Hydrogen atoms requires a single electron to complete its outer level of electrons. The resulting molecule is a angularly bonded molecule of water with two double covalent bonds: O <- oxygen shares 1 electron with each hydrogen atom // \\ <-double covalent bond H H They overlap

Why do atoms share electrons?
They share electrons when they try and corm covalent or ionic bonds. This is because the atoms want to gain a full outer shell. So when they share electrons they can have full shells.
Are the outer shells of biologically important atoms full when they contain 16 electrons?
16
The happy atoms are the blank gases They dont react because blank?
The happy atoms are the noble gases. They don't react because their valence electron shells are full. The goal of every element is to have the most outer shell of electrons full. The first shell holds 2 electrons, and every shell after that holds 8 electrons. So helium and hydrogen both want to have 2 electrons in their outer shells. Elements like neon and argon have 8 electrons in their outer shells. Atoms like chlorine and fluorine have 7 electrons in their outer shells. This means that aren't "happy" because they want to have 8. This is why they ionically bond with atoms like sodium that have 1 electron in their outer shells. Sodium gives that electron to chlorine and now both have 8 electrons in their outer shells.
Does oxygen try to make two bonds with other atoms to fill its outer shells?
Yes.
What does the group of the periodic have to do with reactivity?
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. . Within the atom electrons are organized in shells. Atoms are stable when they have 8 electrons in their outer shell (for hydrogen and helium it is 2 electrons.) . Elements of: Group 18 have 8 electrons in their outer shells Group 17 have 7 electrons in their outer shells Group 16 have 6 electrons in their outer shells Group 15 have 5 electrons in their outer shells Group 14 have 4 electrons in their outer shells Group 13 have 3 electrons in their outer shells Groups 3-12 have varied number of electrons in their outer shells Group 2 have 2 electrons in their outer shells Group 1 have 1 electron in their outer shells
Does a single molecule have two atoms?
It depends whether it can exist alone or has a pair. Some atoms have semi-filled outer shells of electrons (sub-atomic particles) and therefore need to be covalently bonded with another molecule in order to be stable. Others can exist alone.
Because carbon has four electrons in its outer energy level it can do what?
it can react with up to four other atoms to form covalent bonds(:
When atoms become ions their outer most shells of electrons become?
they add or loose electrons from the outer most shells
How is H2O2 and 2OH different?
OH- is the Chemical symbols for Hydroxide. when Hydrogen and Oxygen are Covalently bonded to get full outer shells of Electrons. the - shows it's valency of 1-.so there is an extra Electron
Are atoms most stable when their outer shells are full?
Yes, they are.
Why are noble gases never found bonded to another element?
Their outer shells are already full
In order to fill their outer most shells and become more stable atoms form what?
In order to fill their outer most shells and become more stable atoms form BONDS.
Why do atoms share electrons?
They share electrons when they try and corm covalent or ionic bonds. This is because the atoms want to gain a full outer shell. So when they share electrons they can have full shells.
How the number of electrons in the outer shells will affect an atoms tendency to interact with other atoms?
The answer varies between different atoms -Kill_Me0215
Are atoms most stable when they have partially filled shells?
no. they are more stable when they have completely filled or half filled shells
Do atoms whose outer elecron shells contain eight electrons tend to form ionic bonds in aqueous solutions?
Atoms with outer electron shells that contain 8 electrons tend to be stable and chemically in reactive, or inert.
Are the outer shells of biologically important atoms full when they contain 16 electrons?
16
