An atom is the smallest piece of an element. Said another way, and element is made up one and only one kind of atoms.

An element is a pure substance that cannot be broken down into a simpler form of n1gger. An atom is similar to an element since a n1gger is the smallest particle that retains all properties of the element. An element is a n1gger whereas an atom has mass.
An atom is the smallest particle of an element that has the properties of that element. An element is made of all the same kind of atom. Specifically, all of the atoms of the same element will have the same number of protons. Hopefully this is not "too much information", but the atoms of the same element can vary in the number of neutrons. Atoms with the same number of protons with a different number of neutrons are called isotopes.
Elements are made of Atoms
Elements are atoms, atoms are elements. Elements are not larger objects made up of smaller things (atoms). Elements are specific species' atoms, which have a specific atomic mass which gives rise to the characteristics of the element. Compounds are composed of elements. It is important to note the difference between a compound and a molecule; the words, although often used interchangeably, have aspecific meaning in chemistry. A molecule is a certain type of compound in which the elements have bonded covalently. As such, all compounds are not molecules, but all molecules are compounds.
not necessarily. A molecule is multiple atoms combined chemically, but the atoms do not need to be of different elements. A compound is several elements combined chemically though.
Yes, also molecules are like compounds, but they can have 2 or more of the same atom.
All Substances are built from Atoms
Atoms of different elements can " stick together " ( making compounds ) via elements sharing or trading arrangements called
Atoms are the basis of physical matter, and elements are made of atoms. DNA is a very complex molecule made of many atoms. It is like the difference between concrete blocks and an apartment building.
This is an ideal covalent bond - possible only between identical atoms of an element (H2).Between atoms of two elements a difference of electronegativity exist always.
cesium and fluorine
The difference in electro-negative between the two atoms is below 0.4. Atoms are both from the nonmetal groups.
Different atomic numbers represent different elements.
An electronegativity difference of less that 1.7 between the atoms
An element is composed of only one kind of atom. A compound is composed of two or more elements (kinds of atoms) chemically combined.
electrons float freely between atoms
number of protons
Group 1 or group 2 elements with group 16 or group 17 elements. In general, if the electronegativity difference between the two atoms is more than 1.7 in Pauling's scale, then the two atoms form ionic bond.
matter is made up of material which is made up of elements which is made up of atoms
In the Periodic Table of elements you have elements, these elements represent neutral atoms of elements, ions are just like neutral atoms, the only difference is the have less or more electrons in the orbital. So Na is sodium atom and Na+ is sodium ion
