Contemporary science does not consider water to be an element.
No water is NOT an "atom". No water is NOT an "element".
The atomic number of an element equals the number of protons in the element.
An isotope of an element has the same number of protons but a different number of neutrons. One of the most common is deuterium (heavy water), an isotope of hydrogen that has one neutron instead of the usual zero.
An element "I.D." is an element's atomic number. An element's atomic number shows how many electrons are in an atom of that element. An element's atomic number also determins their position on the Periodic Table.
The number of protons.
There are a number of metals that react with water, such as sodium, lithium, etc., but there is no element that decomposes in water. Decomposition is a characteristic of more complex molecules, not of elements.
No, it is a mixture of a number of different compound. Water itself is a compound. Ocean water is not pure water though.
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
Hydrogen is a non metal element. Atomic number of it is 1.
Water is not an element
No water is NOT an "atom". No water is NOT an "element".
The number of protons in the nucleus of an element gives that element its ATOMIC NUMBER.
The atomic number of an element refers to the number of protons in the nucleus within the element. This is how the element is identified.
Water is not an element, it is made of Hydrogen and Oxygen. Oxygen is the most plentiful element in the human body by weight. If you go by number of atoms, then Hydrogen would be the most plentiful.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
The number of atoms in an element depends on WHAT element AND how much of that element.
By definition, the number of protons in the atoms of an element is the atomic number of the element.
