molecule - Kids | Britannica Kids | Homework Help
A molecule is the smallest unit of a substance that has all the properties of that substance. For instance, a water molecule is the smallest unit that is still water. A water molecule can be divided into tiny parts called atoms. This produces two hydrogen atoms and one oxygen atom. But these atoms alone do not have the properties of water.

Each water molecule is made up of two hydrogen atoms and one oxygen atom. Water Molecule. We know that water isn't always "wet", sometimes it's frozen into ice or snow. Depending on the temperature and energy of the molecules in water, water can exist in three states: Ice - Ice is the solid form of water.
Making up Molecules - All the Same, What's in Water?, Molecule ... - JRank
Water is made of two different types of atoms—oxygen and hydrogen. They join together to make water molecules. Each water molecule has three atoms in it. There are two hydrogen atoms and one oxygen atom. Water molecule. Water is water because of the pattern of atoms in its molecules. The pattern remains the same.
Water (molecule) facts for kids - Kids encyclopedia
2024年9月8日 · Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour.
Kids science: Molecules - Ducksters
Water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. This is why it's called H 2 O. Water will always have 2 times the number of hydrogen atoms as oxygen atoms. There are only just over 100 types of atoms, but there are millions and millions of different types of substances out there.

2023年12月5日 · A water molecule contains 2 hydrogen (H) atoms and 1 oxygen (O) atom. One molecule of water in your glass won't quench your thirst, though. You need LOTS of water molecules, trillions of them. At normal temperatures all those individual water molecules like to stick together and form a liquid (the water in your glass).

Water is made of tiny units called molecules, which are combinations of even smaller units called atoms. A molecule of water is made of two hydrogen atoms and one oxygen atom. The scientific formula for water is H 2 O. Water can be found in three physical states: liquid, solid (ice), or gas (steam or vapor).
