Uranium, Hydrogen, or Plutonium.
An element is a chemical/substance/etc that cannot be broken down any further - that is to say that water can be broken down into Hydrogen and Oxygen, but neither Hydrogen nor Oxygen can be broken down - hence they are Elements.
There are over 100 elements known to man and what makes an element that specific element is the number of protons in the atoms nucleus. Helium has 2 protons in its nucleus. Hydrogen has 1 proton, Oxygen has 8, Carbon has 6. To know how many protons are in an elements atom's nucleus, look at the Periodic Table of Elements and the element's atomic number is the number of protons in the atoms nucleus.
Atoms of the same type. Ex. only gold atoms are found in pure gold.
An element is a substance which cannot be broken down chemically into other substances. Basically it consists of atoms of the same kind.
atom
An atom is not an element on its own. Think of it as a building block for every element in existence. Atoms are what make up the elements.
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
When an atom of an element has a different number of neutrons.
Gold is a Element becuase it is only made up of one atom.
An atom and an element are synonyms. Rather, subatomic particles make up atoms (and elements). The three types of subatomic particles are neutrons, protons, and electrons.

"element" (2 make up a molecule)
1 atom make up the element carbon.It has atomic number 6.
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
they make up the atomic mass of the element.
Sodium is an element- you just need one atom. Its a trick question
Atoms make up compounds and elements.Atoms make up everything in the world.
yes.
an element is any substance composed of only 1 type of atom, such as Oxygen, or Gold. These elements are combined to make up everything that is not an element, such as Water, H20 two hydrogen atoms and one oxygen atom; or table salt, NaCl one sodium atom and one chlorine atom.
When an atom of an element has a different number of neutrons.
H2O two Hydrogen atomss and One Oxygen atom
Gold is a Element becuase it is only made up of one atom.
