Hydrogen I'm sorry "youarewhatyoubelieveyouare", but this answer isn't correct. Oxygen has the higher affinity for electrons... that's why, in a water molecule, each hydrogen has a positive and the oxygen has a double negative charge... the oxygen is attracting more of the electronic cloud towards itself than the hydrogen...

Water (H2O) consists of two elements, hydrogen and oxygen. In water molecules, hydrogen forms a cation (positively charged ion) and oxygen forms the anion (negatively charged ion). Thus, in a water molecule, the oxygen atom is more electronegative.

Where is the density of electrons greatest in the water molecule?

The density of electrons is greatest around the oxygen atom in a water molecule because oxygen is more electronegative than hydrogen, causing it to attract the shared electrons more strongly. This results in a higher electron density around the oxygen atom.


Which atom has the largest electronegativity value?

Fluorine has the largest electronegativity value among all the elements.

Is a water molecule formed from 1 oxygen atom and 1 hydrogen atom?

No. The molecule for water is H2O, meaning each water molecule contains 2 hydrogen atoms and 1 oxygen atom.


What type of bond holds one water molecule to another water molecule?

A hydrogen bond holds one water molecule to another water molecule. This type of bond occurs between the positively charged hydrogen atom of one water molecule and the negatively charged oxygen atom of another water molecule.

How many of each type of atom is in a single molecule of water?

A single molecule of water consists of two hydrogen atoms and one oxygen atom.


How many hydrogen atom are present in each molecule?

Per every water molecule, there are 2 hydrogen atoms and 1 oxygen atom. These atoms make up a water molecule.


What atoms and how many of each are found in a molecule of water?

A molecule of water (H2O) is composed of two hydrogen atoms and one oxygen atom. The oxygen atom forms a covalent bond with each of the hydrogen atoms to create the water molecule.


Why you cannot say ' an atom of water'?

Water is a compound formed by the chemical bonding of two hydrogen atoms and one oxygen atom. An atom refers to a single, indivisible unit of an element, not a compound. Therefore, it is more accurate to say 'a molecule of water' or 'a water molecule' to refer to the smallest unit of water.


What is a water molecule with an extra hydrogen atom called?

A water molecule with an extra hydrogen atom is called a hydronium ion (H3O+). This ion is formed when a water molecule gains a proton, becoming positively charged.
