atoms quiz

• Matter is anything with weight that takes up space as long as anything with mass that takes up space.
• Kinetic energy is motion and the ability to do something.
• Potential energy is the energy that is possessed by an object or its composition.
• Types of matter include solids, liquids, and gasses.
• Temperature affects matter when it increases and decreases.
• When the temperature increases, the particle speed increases, and when it decreases, the particle speed decreases.
• Extensive properties are the amount of matter in an object, for example, mass.
• Physical properties include hardness.
• Physical change can result in boiling, evaporating, melting, or dissolving.
• The law of conservation of matter states that an atom can be rearranged but the amount and type of atom stays the same.
• Non-metals are gasses, brittle, bad conductors of heat and electricity, and are not malleable.
• Metalloids are shiny, ductile, great conductors of heat, and malleable.
• Average atomic mass is the average mass of all the natural isotopes of a specific atom.
• Protons tell you the atomic number.
• Electrons have the smallest weight.
• Isotopes have the same number of protons and electrons but different neutrons.
• Isotopes also have a different mass number but the same atomic number.
• The mass number is at the top of the isotope symbol and the atomic number is at the bottom.
• Protons and electrons are in the nucleus and neutrons orbit the nucleus.
• Electrons can also orbit.
