Atoms are the smallest piece of matter you can get. Elements have only one kind of atom in it.
hydrogen
The most common element in the universe is hydrogen.
All atoms of any single element have the same number of protons and electrons.
By mass, oxygen By atoms, hydrogen
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.
Atoms, ions, and isotopes of an element all have the same number of protons in their nucleus, which determines the element's identity.
Uranium (as an element) has atoms, not molecules; uranium compounds are molecules.
Sugar itself is not an element, hence has no elemental sign. Rather sugar is a composition of elements, for sucrose (common table sugar) that is 12 Carbon atoms, 22 Hydrogen atoms, and 11 Oxygen atoms, or C12H22O11.
All atoms of a single element have the same number of protons in their nuclei, which defines the element's atomic number. This characteristic gives each element its unique chemical properties. Additionally, while they may vary in the number of neutrons (resulting in different isotopes), the electron configuration, which determines how atoms interact with each other, is also consistent among atoms of the same element.
There are no "atoms in an element," but rather atoms OF an element. If you are trying to find the number of atoms in a sample of a pure element you divide its weight by its molar mass and then multiply by 6.022 x 10^23 to get the answer in atoms. The answer options are 2,3, or 4.
Lawrencium is an artificial element obtained at the level of 1 000 -2 000 atoms.
The number of atoms in an element depends on WHAT element AND how much of that element.
