The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key part. From the Periodic Table of Elements, one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams.
H2 is an element as it does not include any other elements from the Periodic Table.
H2 Is a diatomic hydrogen molecule. It is made up of two hydrogen molecules that are joined together.
Zn (zinc) is an element. H (hydrogen) is an element. Cl (chlorine) is an element. H2 (hydrogen gas) is NOT an element.
A molecule can have a variable number of elements. For example, the simplest molecule, hydrogen gas (H2), contains two hydrogen atoms. More complex molecules, such as glucose (C6H12O6), contain multiple elements such as carbon, hydrogen, and oxygen.
The seven diatomic elements are hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2). These elements naturally exist as molecules consisting of two atoms bonded together.

the formula for an ionic compound that contains the elements magnesium and sulfur.Mg + H2 SO4 -> Mg SO4 + H2. .
Chemical Name = Oxygen Chemical Symbol = O There is no chemical formula for elements.

Zn (zinc) is an element. H (hydrogen) is an element. Cl (chlorine) is an element. H2 (hydrogen gas) is NOT an element.
In the reaction N2 + 3H2 → 2NH3, nitrogen (N2) is reduced because it gains hydrogen atoms, and hydrogen (H2) is oxidized because it loses electrons.

Zero. All elements (as well as elemental molecules such as O2, H2, Cl2, etc) have a net charge of 0.
There are seven elements that occur naturally as diatomic molecules: hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2).
Zero: carbon=C Hydrogen=H H2=Hydrogen Gas
Diatomic elements consist of two atoms.The formula of these elements are always written with a subscript 2 in its symbol to indicate its molecular composition.examples: H2,O2.
