Periodic table
This chart organizes all known elements by increasing atomic number.
What is Periodic Table?
This is the basic form of energy that flows through wires to power lights and appliances.
What is electricity
This type of energy is energy of motion. A moving car or rolling ball has this.
What is kinetic energy?
A repeating movement that transfers energy from one place to another
What is a wave?
This is the smallest unit of an element that still keeps the element’s properties.
What is Atom?
This number tells how many protons are in an atom of an element.
What is Atomic Number?
This device is used to open or close an electric circuit.
What is a switch?
This type of energy is stored energy. A stretched rubber band or a book on a shelf has this.
What is potential energy?
This is the distance between two matching points on a wave, such as crest to crest or trough to trough
What is Wavelength?
This part of the atom has a positive charge and is found in the nucleus.
What is proton?
Elements in the same vertical column (group) usually have the same number of these in their outer shell.
What are Valence electrons?
A complete path that allows electric current to flow is called this.
What is Circuit?
This type of energy travels in waves and allows us to see light, feel heat from the Sun, and use microwaves.
What is Electromagnetic wave?
This type of wave moves particles back and forth in the same direction the wave travels.
What is a longitudinal wave?
When two or more atoms chemically bond together, they form this.
What is molecule?
This group of elements is found in Group 18 and is known for being very unreactive.
What are Nobel gases?
This type of circuit has only one path for the current to flow.
What is a series circuit?
This type of energy is stored in food, batteries, and fuels, and is released during chemical reactions.
What is Chemical Energy?
This is highest point of the transverse wave
What is crest?
This type of bond forms when atoms share electrons.
What is Covalent bond
This element is in Period 3, Group 17, is a non-metal, and is commonly used to disinfect swimming pools.
What is Chlorine?
This scientist flew a kite during a thunderstorm to show that lightning is electricity.
Who is Bejamin Franklin?
his type of energy is associated with vibrating objects and requires a medium to travel, such as air or water.
What is sound energy?
This scientist is known as the “father of wave theory of light” and showed that light behaves like a wave through experiments with interference.
Who is Thoman Young?
This number tells how many protons are in an atom and determines the element’s identity.
