Discussion Questions
- Before VideoWhat makes a substance different from an element? ANSWER
Substances are made from different types of atoms. Elements are made of the same types of atoms.
An atom is the basic unit of matter.
Atoms are made of protons that have a positive charge, neutrons that have no charge, and electrons that have a negative charge.
Protons and neutrons are found in the center, called the nucleus. Electrons are found orbiting around the nucleus in areas called energy levels.
Gold, silver, titanium.
Salt is made of sodium and chlorine. Sugar is made of carbon, hydrogen, and oxygen.
- After VideoWhat is an element?ANSWER
Elements are pure substances that are made of only one type of atom.
magnetism, conductivity, melting point
There are 7 rows of the periodic table called periods. The number of each period indicates the number of electron energy levels that are positioned outside the nucleus.
Fluorine can be found in toothpaste and drinking water. Rechargeable batteries in phones and computers are made of lithium.
Elements with similar properties will react with other elements of different properties. The position of an element on the periodic table can help to predict how elements will react with others.
Noble gases are elements in column 18 of the periodic table of elements that share similar properties. They rarely react with anything, but when you pass electricity through them, they glow.
