Classification of Matter
When gas particles are cooled at boiling point and the molecules slow down, causing the matter to build up, similar to the droplets found on the inside of windows. This phase change is called what?
What is Condensation?
What is the name given to the particle that orbits around the center of an atom that also has a negative charge?
What are Electrons?
If Neon has 10 protons and 10 neutrons, the atomic number of Neon is what?

This occurs between metals, losing electrons, and nonmetals, gaining electrons. Ions with opposite charges will attract one another creating a what?
What is an ionic bond?
CH4 + xO2 → CO2 + 2H2O. Find 'x'.
X would equal 2
What is the name used to classify this extremely low density gas that is found at temperatures close to absolute zero?
What is Bose-Einstein Condensate?
The name of the person who created the Bohr Model of the atom, he theorized that an atom has a center that is orbited by negative charged particles.

This metal has the symbol K and is found in bananas. Its atomic number is 19
What is Potassium?
This type of bond involves the sharing of electron pairs between atoms. The bonded atoms share electrons.
What is a covalent bond?
4Al + 3O2 → xAl2O3. Find 'x'
X would equal 2

This is when two or more elements combine to form something new.
What is a chemical compound?
1. FeCl3 + 3NaOH → Fe(OH)3 + xNaCl. Find 'x'
X would equal 3
What is the name used to describe this phase change of bubbling gas particles to the surface when a liquid is heated up?
What is Boiling?
This particle has no electrical charge and is found in the center of an atom.
What are neutrons?
Elements in this column of the periodic table, also known as Group 1A, are characterized by having one valence electron in their outermost shell
What are alkali metals?
1. When Chlorine (non-metal) and Sodium (metal) bond together, the electrons are donated and the new substance would be what state of matter?
The substance would be sodium chloride and it would be a solid
4.C3H8 + 5O2 → 3CO2 + xH2O Find 'x'.
X would equal 4
Oxygen has a boiling point of -183 degrees celsius and a melting point of -219 degrees celsius, this means that at room temperature(22C) oxygen is what state of matter?
What is gas?
When looking at Bohr's model of an atom, electrons orbit the nucleus in specific energy levels. What name is given to these energy levels?
What are shells?
This zig zag line divides the metals from nonmetals in the periodic table.
What is the periodic staircase?
Kind of like a salad, this is when two or more substances are combined but not chemically bonded
