What is an element?

  • An element is a pure substance that cannot be broken down into simpler substances by chemical means. It consists of only one type of atom.
100

What is a compound?


  • A compound is a substance formed when two or more different elements chemically bond together.
100

What is a mixture?


  • A mixture is a combination of two or more substances that are not chemically bonded together.
100

What are the three main states of matter?


  • The three main states of matter are solid, liquid, and gas.
100

What are subatomic particles?


  • Subatomic particles are the smaller particles that make up an atom, including protons, neutrons, and electrons.
200

Name one example of an element.

  • Examples include Hydrogen (H), Oxygen (O), Carbon (C), and Gold (Au).
200

Give an example of a compound.


  • An example of a compound is water (H₂O) or carbon dioxide (CO₂).
200

Name a homogeneous mixture.


  • An example of a homogeneous mixture is salt water or air.
200

Describe what happens during melting.


  • During melting, a solid absorbs heat and changes into a liquid as its particles gain energy and move more freely.
200

What charge do protons have?


  • Protons have a positive charge.
300

What is the atomic number?


  • The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.
300

How do compounds differ from elements?


  • Compounds consist of two or more different elements that are chemically bonded, whereas elements are made of only one type of atom.
300

What is the difference between homogeneous and heterogeneous mixtures?


  • Homogeneous mixtures are uniform in composition, while heterogeneous mixtures have visibly different components.
300

What is evaporation?


  • Evaporation is the process by which liquid changes to gas at temperatures below its boiling point, typically occurring at the surface of the liquid.
300

Describe electrons and their charge.


  • Electrons are negatively charged particles that orbit the nucleus of an atom.

What are energy levels in an atom?


  • Energy levels are regions around the nucleus where electrons are likely to be found, corresponding to different energy states.
500

How are elements organized in the periodic table?


  • Elements are organized by increasing atomic number and grouped based on similar chemical properties.
