It has a different amount of protons, nuetrons and electrons than any other element's atom.
Atoms of these elements do not combine with other atoms, even atoms of the same element, because their valence electron shells are full.
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
A substance that can not be decomposed into simpler substance by a chemical or physical means is a chemical element.
It depends on the substance your are talking about. It could be a compound, mixture, or substance; depending on the substance. If it is an element off the periodic table, it is an element. If it is two elements chemmically combined, it is a compound. If it is two elements that are not chemically combined, it is a mixture.
The subatomic particle that makes atoms of different elements different from each other is the proton. This is given as the atomic number of the element on the periodic table.
Apart from the inert gases which are monoatomic all of the other elements bond to themselves and to atoms of other elements.
It has a different amount of protons, nuetrons and electrons than any other element's atom.
Each element is different so for a certain element to be define/determined it has different atoms to make it up so no other element has the same atoms
number of protons
Nitrogen is an element. It is not contain atoms of other elements. It has no metallic atoms.
There are very many elements which will do that.
Atoms of these elements do not combine with other atoms, even atoms of the same element, because their valence electron shells are full.
Not: atoms The answer is an element
according to my research
It has a different amount of protons, nuetrons and electrons than any other element's atom.
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
This is the relative atomic mass, which compares other atoms to the mass of I atom of the isotope carbon-12.
