Four electron groups - two bonded pairs and two lone pairs
the answer is 2, Water has two electron groups according to the lewis dot structure.
4, 2 hydrogen, and 1 oxyegen.
The electron arrangement in an H2O molecule is as follows: oxygen has 6 valence electrons and forms two single bonds with each hydrogen (1 electron each), along with two lone pairs of electrons on the oxygen atom. This gives oxygen a total of 8 electrons in its valence shell, satisfying the octet rule.
Hello
An electron transport chain couples a reaction between an electron donor(such as NADH) and an electron acceptor (such as O2) to the transfer of H+ ions across a membrane ,through a set of biochemical reactions. These H+ ions are used to produce adenosine triphosphate (ATP) which is the end product of the ETC.
hydorgen: 1 electron Oxygen: 8 electrons Therefore 10 electrons
Oxygen is the final electron acceptor of the electron transfer chain. Hydrogen ( protons ) come down their concentration gradient and through the ATP sythase making ATP. Then they, with the electrons oxygen accepts, become H2O.
Electron geometry for this is tetrahedral. There are two O-F single bonds, which makes 2 electron groups. There are two lone pairs around oxygen, which make up the last two electron groups. Molecules with four electron groups has a tetrahedral Electron geometry.

The electron arrangement in an H2O molecule is as follows: oxygen has 6 valence electrons and forms two single bonds with each hydrogen (1 electron each), along with two lone pairs of electrons on the oxygen atom. This gives oxygen a total of 8 electrons in its valence shell, satisfying the octet rule.
The atomic mass of H2O is 18.01528amu. Each hydrogen atom has a mass of 1.00794amu and the oxygen atom has a mass of 15.9994amu. There is not atomic number for H2O, as it is a compound, not an element. H: 2 x 1.00794amu = 2.01588amu O: 1 x 15.9994amu = 15.9994amu Total = 18.01528amu
It has a bent structure just like the H2O and H2S.
