Ammonium nitrate contain 3 chemical elements.
Carbonic acid has the formula H2CO3. Each capital letter indicates a different element. Therefore, there are free different elements present: hydrogen, carbon and oxygen.
the number of the elements that is present in a compound
Isotopes are atoms of the same elements with different number of neutrons.
The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
About 75 metals.
molecular formula
Carbonic acid has the formula H2CO3. Each capital letter indicates a different element. Therefore, there are free different elements present: hydrogen, carbon and oxygen.
Yes, atoms of different elements have a different number of protons.
Because different elements have different numbers of protons, which determines the atomic number.
the number of the elements that is present in a compound
Atomic number indicates the amount of protons present in the nucleus of an atom.
All atoms have a definite pattern of arrangement of electrons around their nucleus but the number of electrons that are present around the nucleus are different for each element
According to the present there are around 116 different elements discovered. With nuclear reactions, new types of atoms can be formed. Henceforth, the number may increase by the future.
Isotopes are atoms of the same elements with different number of neutrons.
Of the 92 elements from hydrogen to uranium 90 of them are present in some amount in the crust of the earth. Trace amounts of plutonium and other transuranics are also present.
No, the number of protons defines what element an atom belongs to. If two atoms are of different elements then they have different number of protons.
Different elements have different numbers of protons. The number of protons identifies the element.
