Yes, O2 is a covalent bond.
8 valence (outer-shell) electrons is a stable configuration, which is what every atom is trying to achieve.
There are only 6 valence electrons in one single oxygen atom, which means it is looking for another two valence electrons.
Since both oxygen atoms don't want to lose any valence electrons but want to gain two valence electrons, this means that they must each share two of their own with the other atom. Hence both atoms then have eight valence electrons. But because of their sharing electrons, they are stuck together because neither wants to lose their own two valence electrons. This is a covalent bond.
H2O (water) has a covalent bond between the hydrogen and oxygen atoms. In a covalent bond, the atoms share electrons to form a stable molecule.
No. Although the bonds in H2O are covalent, they are not coordinate covalent bonds.
KCl does not contain a coordinate covalent bond as it is an ionic compound. HF, H2O, and F2 contain coordinate covalent bonds, where a shared pair of electrons comes from one atom (donor) to form the bond.
it is a polar covalent bond. Scince oxygen does not follow the octet rule(only 8 electrons, needs ten) and hydrogen has one electron, two hydrogen electrons plus eight oxygen electrons equal ten :)
No. The H2O molecule contains only single covalent bonds.
H2o
H2O (water) has a covalent bond between the hydrogen and oxygen atoms. In a covalent bond, the atoms share electrons to form a stable molecule.
No. Although the bonds in H2O are covalent, they are not coordinate covalent bonds.
H2O has a covalent bond between Hydrogen and Oxygen atoms. They share electrons and hence achieve noble gas configuration. The covalent bond present is a polar bond.
The bond formed with carbon is essentially the covalent bond. So all the organic molecules in your body has got covalent bond.
KCl does not contain a coordinate covalent bond as it is an ionic compound. HF, H2O, and F2 contain coordinate covalent bonds, where a shared pair of electrons comes from one atom (donor) to form the bond.
H2O has polar covalent bonds, not non-polar covalent bonds.
it is a polar covalent bond. Scince oxygen does not follow the octet rule(only 8 electrons, needs ten) and hydrogen has one electron, two hydrogen electrons plus eight oxygen electrons equal ten :)
No. The H2O molecule contains only single covalent bonds.
H2O has a stronger bond then CaO because H2O is a covalent compound (made up of two nonmetals), whereas CaO is an ionic compound (made up of both a metal and nonmetal), and covalent bonds are stronger then ionic bonds.
H2O does not have any ionic bonds. The bond between the oxygen and hydrogen atoms in water is a polar covalent bond, where electrons are shared unequally leading to a slight negative charge on the oxygen and a slight positive charge on the hydrogens.
Water's chemical formula is given in the question.
