Atomic Structure
This positively charged particle is found inside the nucleus.
What is a proton?
Two or more different elements chemically joined together.
What is a compound?
What is a solid?
This state of matter has a definite shape and definite volume.
Heat moving through direct contact between two objects is called this.
What is conduction?
Density tells us how tightly this is packed into a certain amount of space.
What is density?
This particle has no charge and is found in the nucleus.
What is a neutron?
In this type of bond, atoms SHARE electrons.
What is a covalent bond?
What is melting?
This change of state happens when a solid becomes a liquid.
Heat transfer caused by the movement of liquids or gases is called this.
What is convection?
Complete the formula: Density = mass _____ volume.
What is divided by?
This negatively charged particle moves around the nucleus in energy levels or shells.
What is an electron?
In this type of bond, an electron is transferred from one atom to another.
What is an ionic bond?
What is evaporation or vaporization?
This change happens when a liquid becomes a gas.
Heat traveling through electromagnetic waves is called this.
What is radiation?
A rock has a mass of 30 g and a volume of 10 mL. What is its density?
What is 3 g/mL?
How many protons, neutrons, and electrons does a neutral lithium atom have?
3 protons, 3 neutrons, 3 electrons.
H₂O is not an element. Explain why.
It contains two different elements, hydrogen and oxygen, chemically bonded together, so it is a compound.
What is sublimation?
Change directly from a solid to a gas.
You touch a hot metal pan and your hand becomes hot. What type of heat transfer occurred?
What is conduction?
An object has a density of 0.8 g/mL. Will it sink or float in water?
It will float.

What happens to the energy and movement of particles when ice melts?
The particles gain energy and move more freely/faster.

Wow, incredible job!
Aluminum has a density of 2.7 g/cm³ and cork has a density of 0.24 g/cm³. Which one floats in water, and why?
Cork, because its density is less than water's density of 1.0 g/mL.
