Why do two oxygen atoms must share four electrons when they form a covalent bond?
Atoms undergo chemical bonding in order to achieve stable valence shells. In order for oxygen atoms to accomplish this when they bond together, they share two pairs of valence electrons, which is a double bond.
Why do atoms tend to bond to other atoms?
When two atoms need to gain same amount of electrons, they tend to share. That is when bonds are formed. Ex. One atom of oxygen needs two electrons to attain its octet. Another atom of oxygen will also need two electrons. Since both the atoms need electrons they begin to share their electron in the outermost shell. They form double bond since they need two electrons.
What happens to the sulphur particles in order for them to become sulphur dioxide particles?
well sulfur dioxide is a covalent compound so the sulfur atoms and the oxygen atoms share valence electrons. This is because all three atoms must try to have an octet, and with only 18 total valence electrons this must be done through sharing. So to become sulfur dioxide, the valence electrons on the oxygen atoms must be shared with the valence electrons on the sulfur atom.
Do O2 molecules contain covalent bonds?
Yes, the oxygen molecule O2 has covalent bonds. The oxygen atoms share their electrons.
Why would two oxygen atoms want to form a double covalent bond?
A lone oxygen atom has 6 electrons in its outer shell which is not very stable, whereas as full octet (8 outer shell electrons) is stable. In order to achieve this two oxygen atoms will share 4 electrons, each contributing 2 electrons. Since these electrons exist within the orbitals of both atoms, to oxygen atoms essentially achieve a full octet.
How many electrons that an atom in the oxygen family gain or share?
Atoms in the oxygen family can gain or share two electrons in order to achieve an octet of electrons.
What happen when the oxygen atoms share electrons?
A covalent bond is formed.
How many paire of electrons do the two oxygen atoms in an oxygen molecule share with each other?
They share two pairs of electrons and have 2 lone pairs
What happens to the number of valence electrons when atoms combine to form a compound?
They Share Electrons
What happens to most atoms when they combine with other atoms to form compounds?
they share electrons
What property of oxygen makes it share electrons unequally with hydrogen atoms?
Oxygen atoms have a greater electronegativity than hydrogen atoms. Electronegativity is the ability of an atom in a molecule to attract electrons to itself.
What happens when oxygen share electrons?
They form covalent bonds.
What will oxygen do with its electrons to gain stability?
Oxygen will bond (share electrons) with other atoms to produce stable compounds ex. H2O ,O2
What happens when 2 nitrogen atoms share electrons?
they form a covalent bond
"atoms share electrons"?
Atoms share electrons when they form covalent bonds.
Why do two oxygen atoms must share four electrons when they form a covalent bond?
Atoms undergo chemical bonding in order to achieve stable valence shells. In order for oxygen atoms to accomplish this when they bond together, they share two pairs of valence electrons, which is a double bond.
Does the compound nitrous oxide transfer or share electrons?
Yes, electrons are transferred between the nitrogen atom and oxygen atoms.
