All atoms of the same element have the same number of protons in the nucleus and consequently have the same atomic number. All atoms of the same neutral element have the same number of electrons as well.Know More
Atoms of an element usually have the same number of neutrons as protons. Atoms of the same element that have a different number of neutrons are called isotopes. Isotopes have the same atomic number but different atomic masses.
Atoms of an element share that element's chemical and physical properties, such as boiling point, melting point and stability.
An element is the simplest form of matter and cannot be broken down further by chemical means. There are 118 known elements, arranged in the periodic table in order of atomic number. Of these elements, only the first 98 are naturally occurring. The other elements have been produced artificially or as a result of nuclear reactions.
Atoms of the same element that are arranged in different molecular formations are called allotropes. Allotropes may have different physical appearances and different characteristics such as electrical conductivity. For example, a diamond, coal and soot all are allotropes of carbon. The carbon atoms in a diamond have a tetrahedral structure around each.Learn more in Atoms & Molecules
All isotopes of the same element share a common number of protons and electrons, though they vary in their relative numbers of neutrons. All isotopes of a given element are chemically identical, and they form bonds with other elements in the same way regardless of their neutron count or intrinsic stability.Full Answer >
Atoms that have the same atomic number but different atomic masses are called isotopes. The difference in mass arises due to the atoms containing a different number of neutrons for the same number of protons.Full Answer >
All isotopes of a given element must share the same atomic number, which equals the number of protons. An isotope is denoted by its atomic number in the lower left-hand corner next to its chemical symbol and its mass number in the upper left next to the symbol.Full Answer >
Hydrogen is the only element that does not contain any neutrons in its nucleus. Hydrogen is comprised of one proton and one electron. It is a diatomic molecule, which means that it typically exists as two hydrogen atoms joined together.Full Answer >
