Atoms are the building blocks of everything; they are made up of neutrons, protons, and electrons (and recently it has been discovered that these 3 things are made of quarks). Each atom is one piece on its own, floating around and attaching to other atoms.
An element is a substance that is made up of only one type of atom. Once the atoms cling to each other they form different substances; if only one type of atom (which means that all atoms have the same number of electrons) is combined then it forms an element. If multiple different atoms cling together it forms other substances.
Ex) When atoms with only 1 electron gather they form the element Hydrogen
When atoms with 8 electrons gather they form the element Oxygen
When 2 atoms with only 1 electron cling to one atom with 8 electrons, you end up with 2 Hydrogen atoms that have now mixed with 1 oxygen atom which forms the compound H2O or water; this compound (water) is no longer an element.
atoms are what make up an element
Elements are the items on the Periodic Table; gold, carbon, oxygen, things like that.
An atom is the smallest possible unit of that element. If you put a bunch of identical atoms together, you still have that element.
Another way of putting it; if I had a bar of gold, and I kept splitting it into smaller and smaller bits, eventually I would have gold nuggets, then gold slivers, and finally gold atoms.
can we call sodium an atom and element both?
An element is a specific atom with a set atomic number.

An atom is the smallest piece of an element. Said another way, and element is made up one and only one kind of atoms.
Atoms are smaller
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
biology
To understand, you first need to understand the difference between an element and a compound. An element is any element from the Periodic table. For example, oxygen. A compound is a substance in which more than one element are bonded chemically. This is not to be confused with a mixture, which is simple a mixture of substances with no chemical bonding. An example of a compound would be water, consisting of hydrogen and oxygen bonded together.Now that we've established to difference between an element and a compound, we can explore what the smallest particle of each is. The "smallest particle" is the smallest you can go while still keeping the properties of the original substance.The smallest particle of an element would be an atom. But when dealing with compounds, if you break them down to atoms, then those atoms don't have the same properties as a compound. The smallest particle of a compound is a molecule. In our example of water, a water molecule consists of two hydrogen atoms and one oxygen atom, chemically bonded together. The molecule, consisting of three atoms, has the chemical properties of water. But if you break it down so you just have an oxygen atom and two hydrogen atoms, none of them would have the properties of the original compound (water).Thus, the smallest particle of an element is an atom, and the smallest particle of a compound is a molecule. The difference between the two is that an atom is an atom, and a molecule is two or more atoms chemically bonded.
The Atomic Mass is the total mass of all the sub atomic particles (i.e. the mass of the whole atom): Electrons, Neutrons and Protons. Therefore, it identifies isotopes (as they have different number of sub atomic particales - even for the same element) and thus total mass differs. There can be a fair amount of difference between the Atomic Mass of the most common isotope of an element and its Atomic Weight - which is averaged (weighted average). This makes a difference for single atom calculations, but makes little real difference in bulk calculations.
The difference is the number of neutrons contained in the atom's nucleus
an atom is the smallest unit of an element, but an element is a pure substance
I do not know i am gust a kid and this is my homework.
NOTHING! An atom is just another name for an element!!
An element of gold is made up of many gold atoms, and an atom of gold is only one atom.
An element of gold is made up of many gold atoms, and an atom of gold is only one atom.
The difference between a hydrogen atom and atomic hydrogen is that the "hydrogen atom" represents one atom of the chemical element hydrogen. Atomic hydrogen are isolated hydrogen atoms.
An atom is a particle the smallest of an element. An element is a substance made up of many atoms of ONE kind (or molecules consisting of two or more identic atoms)
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
An atom is a nucleus of protons and neutrons with electrons orbiting around. An element is an atom with a specific amount of protons, neutrons, and electrons. A molecule is a bunch of atoms stuck together.
Nothing, it's the same thing.
Element's have only one atom, while compund's have more that one atom.
An element is a substance that contains only one type of atom (e.i. Carbon). A compound is a substance that is constructed of multiple types of atom (i.e. water [H2O]).
