Hydrogen bonds can form between water molecules because the oxygen atom in water is slightly electronegative, pulling electron density towards itself. This creates a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms. The partially positive hydrogen atom of one water molecule is attracted to the partially negative oxygen atom of another water molecule, forming a hydrogen bond.

Does water have more hydrogen bonds than salt water?
Yes, pure water has more hydrogen bonds because hydrogen bonds are formed between water molecules. In salt water, some water molecules are displaced by salt ions, reducing the number of hydrogen bonds between water molecules.
What type of bonds hold separate water molecules together?
Hydrogen bonds hold separate water molecules together. This type of bond forms between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another water molecule.
When water evaporates do the covalent bonds between O atoms and H atoms break or do the hydrogen bonds break and why?
When water evaporates, it is the hydrogen bonds between water molecules that break, not the covalent bonds within each water molecule. The hydrogen bonds are weaker intermolecular forces that hold water molecules together. Breaking these bonds allows the water molecules to escape as vapor.
What is water-water bonds called in a beaker of water?
In a beaker of water, the bonds between water molecules are called hydrogen bonds. These bonds are formed between the positively charged hydrogen atoms of one water molecule and the negatively charged oxygen atom of another water molecule.
What type of bond does H2O and NH3 have together?
H2O (water) has hydrogen bonds between its molecules. NH3 (ammonia) has hydrogen bonds between its molecules as well, in addition to covalent bonds within the molecule itself.
How do bonds form between water molecules?
The bond between water molecules is known as a hydrogen bond.
What takes away water molecules as molecules are combined?
The intermolecular bonds between water molecules are hydrogen bonds.
What is between the molecules of liquid water?
Water molecules are linked by hydrogen bonds.
Does water have more hydrogen bonds than salt water?
Yes, pure water has more hydrogen bonds because hydrogen bonds are formed between water molecules. In salt water, some water molecules are displaced by salt ions, reducing the number of hydrogen bonds between water molecules.
What determines the cohesiveness of water molecules?
The cohesiveness of water molecules is determined by hydrogen bonds. These bonds form between the hydrogen atoms of one water molecule and the oxygen atoms of neighboring water molecules, creating a strong attraction that allows water molecules to stick together.
What are waters bonds?
Water has two main bonds: hydrogen bonds between other water molecules, and a covalent bond between hydrogen and oxygen.
What bond is found between water molecules?
Hydrogen bonds are found between water molecules. These bonds are formed between the oxygen atom of one water molecule and a hydrogen atom of another water molecule.
Where are the weak Hydrogen bonds located?
Hydrogen bonds occur between polar molecules such as water.
What type of bonds hold separate water molecules together?
Hydrogen bonds hold separate water molecules together. This type of bond forms between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another water molecule.
When water evaporates do the covalent bonds between O atoms and H atoms break or do the hydrogen bonds break and why?
When water evaporates, it is the hydrogen bonds between water molecules that break, not the covalent bonds within each water molecule. The hydrogen bonds are weaker intermolecular forces that hold water molecules together. Breaking these bonds allows the water molecules to escape as vapor.
What kind of bonding does water make?
Water is composed of molecular bonds, but forms hydrogen bonds with other water molecules. Hydrogen bonds are not actual bonds, but they cause an attraction between the water molecules, which is why water is adhesive.
What kind of bond does water commonly make?
Water is composed of molecular bonds, but forms hydrogen bonds with other water molecules. Hydrogen bonds are not actual bonds, but they cause an attraction between the water molecules, which is why water is adhesive.
