What makes a substance different from an element?

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.

What are the different parts of an atom?

Atoms are made of protons that have a positive charge, neutrons that have no charge, and electrons that have a negative charge.

Where are the different parts of an atom located?

Protons and neutrons are found in the center, called the nucleus. Electrons are found orbiting around the nucleus in areas called energy levels.

What makes salt different from sugar?

Salt is made of sodium and chlorine. Sugar is made of carbon, hydrogen, and oxygen.

Elements are pure substances that are made of only one type of atom.

Give three examples of properties of elements.

magnetism, conductivity, melting point

What do the rows of the periodic table indicate?

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.

Give two examples of where you would find elements in our everyday lives.

Fluorine can be found in toothpaste and drinking water. Rechargeable batteries in phones and computers are made of lithium.

How can you use the periodic table to help predict reactivity?

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.

What are noble gases?

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.

WHAT ARE ELEMENTS?

Elements are pure substances made of only one type of atom. An atom is made of protons, neutrons, and electrons. For example, a carbon atom has 6 protons, 6 neutrons, and 6 electrons. This gives carbon unique properties that can be used to identify it. There are 118 naturally occurring elements, each one has a different number of protons.

Elements are made of the same types of atoms.

Elements are naturally occurring substances that exist in all three states—solid, liquid, and gas. Elements are made of the same types of atoms. For example, oxygen exists naturally as a diatomic element, meaning that it has two oxygen atoms. Each atom is made of protons, neutrons, and electrons. Protons and neutrons are positioned in the center of the atom called the nucleus, and electrons are found in the outer portions of the atom called energy levels, or electron orbitals.

All elements have properties.

All elements have properties. Those properties include, but are not limited to, conductivity, magnetism, melting point, boiling point, color, state of matter, and others. Elements with similar properties are grouped together in different areas of the periodic table of elements. Observing an element’s properties allows scientists to categorize it and also determine its reactivity with other elements. Where the element is positioned on the periodic table will determine how it combines, or doesn’t, with other elements.

Elements are arranged in a pattern on the periodic table.

The pattern in which elements are arranged on the periodic table helps scientists categorize them based on properties and reactivity. Each period (row) of the periodic table is associated with the number of energy levels that orbit a nucleus. Row 1 has one energy level; Row 2 has two energy levels; Row 3 has three energy levels, and so on, up to 7. The number of electrons orbiting the nucleus of an atom will determine how that element interacts with other elements.

Different groups of elements have different properties.

The properties of elements, including but not limited to density and reactivity, can be predicted based on their arrangement in the periodic table. For example, as you move across a period, density usually increases. Because of this, an equal sized cube of titanium, iron, and copper may all have the same volume but will have different densities. Other properties of elements can be predicted from the periodic table as well including state of matter, reactivity, and conductivity.

Elements are in our everyday lives.

The element lithium is found in lithium batteries that power your phones, computers, and nearly all rechargeable devices. Fluorine atoms can be found in drinking water and toothpaste. It fights cavities and tooth decay. Calcium is needed to form bones and the shells of living things. Bismuth is found in medicine to treat diarrhea and helps people to feel better from an upset stomach. Iodine is used as a skin disinfectant, especially, when someone has surgery. Chromium is used to make shiny rims on new cars. Copper is used inside electrical wire to conduct electricity.
