Elements, Compounds, Mixtures - Montgomery County Public … from atoms of other elements. Atoms may stick together in well-defined molecules or may be packed together in large arrays. Different arrangements of atoms into groups compose all substances. • Atoms and molecules are perpetually in motion. Increased temperature means greater average energy of motion, so most substances expand when heated. In solids, the … Chem4Kids.com: Elements & Periodic Table The atoms for each element are unique, even though they are all made of similar subatomic parts. Remember that 'atom' is the general term. Everything is made of atoms. The term 'element' is used to describe atoms with specific characteristics. There are almost 120 known elements. For example, you are made up of billions of billions of atoms but ...

Elements and Compounds Printable Worksheets - TeAch … Elements, as previously described, have the same type of atoms in their structure. One element gets a single entry in the periodic table. They have fixed atomic numbers and cannot be broken down into simpler parts. However, atoms of an element might give rise to different atomic mass due to the difference in neutrons of the atoms that make it up. This difference in neutrons gives … Atoms, Molecules, and Compounds Other elements contain two or more atoms in their molecular form (Fig. 2.8). Hydrogen (H 2), oxygen (O 2), and chlorine (Cl 2) molecules, for example, each contains two atoms. Another form of oxygen, ozone (O 3), has three atoms, and sulfur (S 8) has eight atoms. All elemental molecules are made of atoms of a single element. Molecules of compounds have atoms of … Basic Atomic Structure Worksheet Key - Neshaminy School District gives the "identity" of an element as well as its location on the periodic table.
