Atoms
These two sub-atomic particles are found in the nucleus of an atom.
What are protons and neutrons?
These are the states of matter.
What are solid, liquid, and gas?
This chart is used to represent information about elements.
What is the Periodic Table of Elements?
Scientists use these to distinguish between elements and categorize them.
What are properties of elements?
This is the largest living mammal on earth.
What is the blue whale?
This is where electrons are found in atoms.
What is electron cloud?
This is the smallest possible unit of matter.
What is a particle?
This number tells you how many protons an element has in its atoms.
What is the atomic number?
These are the three different categories of elements.
What are metals, nonmetals, and metalloids?
This former planet in our solar system is no longer considered a planet because it is to small.
This sub-atomic particle has a negative charge.
Electron
This is anything that has weight and takes up space.
What is matter?
The field of science that studies elements and their properties, as well as atoms and particles.
What is chemistry?
This category of element is shiny, magnetic, and conducts electricity.
What is metal?
This is the largest reptile species currently living on the Earth.
What is the saltwater crocodile?
This word comes from the Greek word "atomos" meaning "indivisible" or "uncuttable," reflecting the ancient belief that they were the smallest possible particle.
What is "atom?"
This is how big a particle is in comparison to the width of human hair.
What is 100,000 times smaller?
This element is the most commonly occurring element on Earth. It makes up about 46% of the Earth's mass.
This category of element includes elements that are often gas at room temperature, and do not conduct electricity well or create heat.
What are nonmetals?
These structures carry genetic information in our cells.
What is DNA?
This unit of measurement is used to measure the size of atoms.
What are picometers?
This idea states that all matter is composed of tiny, invisible particles that are constantly moving and have spaces between them, with the arrangement and movement of these particles determining the state of the matter (solid, liquid, or gas).
What is the Particle Model of Matter?
This is how you calculate how many neutrons an element has.
What is atomic mass - atomic number?
This is the name for the vertical columns on the periodic table.
What are groups?
Cumulus, cirrus, and stratus are the different forms of these masses of water.
What are clouds?
