Protons vs. Electrons
Proton is a stable particle with positive charge equal to the negative charge of an electron. It is also found in nucleus and it is made from quarks.
Electron is an elementary particle with negative charge. It is also spinning around the nucleus. It can also be found in a lightning.
Matter vs. NRG
Matter is anything that takes up space or anything that has mass.
NRG is not matter, it is an ability to do work or cause change.
*Mass vs. Weight
Mass is the amount of matter inside an object. Uses kg or g as units. It also stays the same.
Weight is the amount of force put on the object by gravity. Uses newtons as units. It also changes itself depending on the position. (Ex. On the moon, on the poles.)
Solute vs. Solvent
Solute (dissolute) is a mixture that is added to the solvent, where the solvent dissolves it. The process is called a chemical change. (Chemical change – a change in matter that produces one or more new substances.)
Solvent (dissolvent) is a substance that is mixed with the solute.
(Ex. Cedevita: solute = powder, solvent = water)
Homogeneous vs. Heterogeneous
Homogeneous mixture is a mixture where you can’t see the different parts. (Ex. Alcohol.)
Heterogeneous mixture is a mixture where you can see the different parts because everything is grouped up. (Ex. Sperm.)
*Capacity vs. *Volume
Capacity is the amount of matter an object can contain.Volume is the amount of 3-dimensional space occupied by an object.
*SI is the metric system that measures them. Here is the list of some other chemistry-related vocabulary words.
Shape – a 3-dimensional geometric shape.
States of Matter – a distinct state of matter in a system; matter that is identical in chemical composition and physical state and separated from other material by the phase boundary.
Molecular Motion – the movement (average) of particles in a state of matter.
Molecular Proximity – distance of particles in a state of matter.

Last thing Ms. D said is the relation to today’s world; if someone would solve the Filament state of matter, and make it be together and stay for more than one second, that person would create a whole new type of energy, more efficient one. So, that means that no more oil or gas needs to be spent. After the long reviewing session, Ms. D showed us the assignments for homework, located on Moodle.
Due Friday, May 28th:
1. The 7th Blog Comment. Remember, you must have three 8th grade comments, three 7th grade comments and two 6th grade comments.
2. Color in the TWO Periodic Tables in your packet - be sure to read the directions for what you need to do for each.
