Radioactive decay occurs when atoms of an unstable element?
It means that massive nuclei break apart.
How is Tungsten formed?
Tungsten is an element - this means that most of the atoms that make up a piece of tungsten were here before the Earth was formed. Most of them were probably created in stars, and released in supernova explosions.
What is the source of radio activiy?
Radioactivity is caused by unstable atoms, that break apart.
How do radioisotopes of an element differ feom other isotopes?
Radioisotopes are "radioactive isotopes"; they are not stable. Radioactive atoms will decay, or break apart into other atoms, by emitting an electron, or a neutron or a positron or an alpha particle (2 protons and two neutrons). The rate at which this happens is measured by the "half-life"; after one half-life, half of the atoms will have decayed. After another half-life, half of the remaining atoms will have decayed. Atoms with short half-lives are highly radioactive, and can be fairly dangerous. Atoms with long half-lives are only slightly radioactive, and aren't all that dangerous.
A substance that is made up of atoms of more than one element is a what?
compound
What are the common molecules for neptunium?
Neptunium contain atoms, not molecules.
What is created when chemicals reactions join atoms together?
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.
What is created when chemicals reactions jion atoms togethter?
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.
The basic particle from which all elments are mad is a molecule?
An element is formed from atoms; atoms are formed from protons, neutrons and electrons.Protons and neutroms are formed from quarks and gluons.A molecule is formed fro atoms.
How many atoms are in ununseptium?
Ununseptium is a chemical element formed from atoms and doesn't contain inside atoms.
What makes a compound and an element?
A chemical compound is formed from chemical elements.A chemical element is formed from atoms; atoms contain an atomic nucleus (protons and neutrons), electrons and...vacuum.
What element has formed the largest numbers of atoms?
The most common element in the universe is hydrogen.
What is water because it is formed from atoms of two element?
It is a Gas,and liquid Water is a COMPOUND because it is formed from atoms of two elements.
What are formed when atoms of one element chemically join with another element?
A compound or compound substance.
Is gold an atom or a molecule?
Gold is a chemical element formed from atoms.
Is aluminum a discrete atom?
Aluminium is chemical element formed from atoms.
Why is ozone not an element?
Ozone is not an element. It is a molecules. The molecule of ozone is formed by the combination of three oxygen atoms(where oxygen is an element).
