What are the elements that make H2O?
A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O.
What symbol is H2O?
H2O
Water/Formula
What is the formula H2O?
How do I make water?
In theory, it’s easy to make water from hydrogen gas and oxygen gas. Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto—instant water.
What is Periodic Table of water?
The periodic table of elements only includes individual chemical elements. Water is not found on the periodic table because it does not consist of a single element. An element is a form of matter than cannot be broken down into simpler particles using any chemical means. Water consists of hydrogen and oxygen.
What is meant by h20?
The chemical symbol (see also symbol) for water. Each molecule of water contains two atoms of hydrogen (H) joined to a single atom of oxygen (O).
How do you make H2O?
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.
Why is water called H2O?
The scientific name for water is H2O. It is called H2O because it has two atoms of hydrogen (H) and one atom of oxygen (O). Water molecules move so fast that they actually break apart from each other and escape into the air as water vapor or steam.
Is a water alive?
Water is not a living thing, and its neither alive or dead.
Is h20 an element?
An element is a substance composed of a single type of atom. Hydrogen (element symbol H) and oxygen (element symbol O) are examples of elements. You may have heard water called “H2O.” The name refers to the chemical formula of water, H2O. So, water is made from elements, but is not itself an element.
What is H2O formula?
What are the 2 trends in the periodic table?

Non metallic character trend on Periodic table. Electronegativity trend in Periodic table. Electron affinity trend in Periodic table. Ionization energy trend in periodic table. Summary of trends in periodic table.
What is the highest element of periodic table?
Copernicium is the heaviest known element on the periodic table, with 112 protons in its nucleus and an atomic mass 277 times heavier than hydrogen.
What element on the periodic table has 2 protons?
The nucleus of the atom of the element helium (He) has two protons (hence helium has an atomic number of 2) and two neutrons. Neutrons have the same weight as protons but no electrical charge.
What are 2 liquids on the periodic table?
The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature. Point at or click an element in the periodic table for more information:
