Water is H2O. The hydrogen molecule has 1 electron and it needs to fill the first shell. Oxygen has a complete first shell and six electrons in the second. The second shell needs eight to be complete. So a bond of two hydrogen atoms and one oxygen molecule is very stable. The way the two elements combine has the oxygen molecule in the middle and the two hydrogen atoms in a tetrahedral pattern.
What else can I help you with?
Is this a fact or a opinion Water expands when it is frozen?
This is a fact. Water molecules form a crystal lattice structure when frozen, causing the molecules to move farther apart and the volume to increase, leading to expansion.
How many water molecules bond together to form an ice crystal?
Ice crystals are made up of many water molecules bonded together in a hexagonal lattice structure. Each water molecule in the lattice is connected to four neighboring water molecules through hydrogen bonds, creating a rigid and ordered structure typical of ice.
What particles are present in a crystal?
A crystal is composed of a repeating pattern of atoms or molecules arranged in a specific and orderly structure. This atomic arrangement creates a lattice structure within the crystal. Therefore, the primary particles present in a crystal are atoms or molecules that form this lattice structure.
Are molecules further apart in ice than in water?
Yes, in ice, water molecules are in a more organized structure compared to when they are in liquid form. This results in a hexagonal lattice arrangement in ice, causing the molecules to be more spread out and creating a lower density compared to liquid water.
What is ionic compounds that absorb water into their solid structure form?
Ionic compounds that absorb water into their solid structure form are known as hygroscopic compounds. These compounds have a strong affinity for water molecules and can readily absorb moisture from the surrounding environment. Examples include salts like calcium chloride and sodium hydroxide.
Is water a lattice?
Water itself is not a lattice; it is a liquid composed of H₂O molecules. However, in its solid form, ice, water molecules arrange themselves into a crystalline lattice structure due to hydrogen bonding. This lattice structure is responsible for ice's lower density compared to liquid water, allowing it to float. In summary, while water as a liquid does not form a lattice, its solid state (ice) does exhibit a lattice arrangement.
Is this a fact or a opinion Water expands when it is frozen?
This is a fact. Water molecules form a crystal lattice structure when frozen, causing the molecules to move farther apart and the volume to increase, leading to expansion.
Is the chemical name and compound name the same for BaCl2.2H2O?
It's barium chloride, and the 2 water molecules are the water of crystallization necessary to form a crystal lattice structure.
Is water molecular or lattice?
Water is primarily molecular, consisting of individual H₂O molecules held together by hydrogen bonds. In its solid form, ice, water can exhibit a lattice structure due to these hydrogen bonds, forming a crystalline arrangement. However, in its liquid state, water exists as a dynamic collection of molecules rather than a fixed lattice.
When water changes to solid the molecules what?
When water changes to a solid (ice), the water molecules slow down and arrange themselves into a crystal lattice structure. This allows the molecules to form a regular pattern, resulting in the solid state of matter.
Are molecules further apart in ice or water?
Molecules in ice are more spread out compared to water as they form a more rigid and ordered lattice structure. This is due to the expansion of water molecules as they freeze into ice.
How many water molecules bond together to form an ice crystal?
Ice crystals are made up of many water molecules bonded together in a hexagonal lattice structure. Each water molecule in the lattice is connected to four neighboring water molecules through hydrogen bonds, creating a rigid and ordered structure typical of ice.
Ice tends to form at the?
surface of bodies of water where the temperature is at or below freezing. The cold air cools the water, causing the molecules to slow down and form a solid lattice structure. As more molecules freeze, the ice expands and floats on top of the water.

Match the description to the form of water that is described?
Water vapor is the least dense form of water, and the molecules are farthest apart from each other. Liquid water is the densest form of water. In ice, molecules form a crystal lattice.
What is ionic compounds that absorb water into their solid structure form?
