Chapter One
Always have to wear these during a lab
What is goggles
Physical properties of matter
Things that can be determined with senses or measuring, color, odor, size, and phase
What is a subatomic particle?
What is a valence electron?
Electrons in the outermost part of the substance. Important because they react and interact with other atoms
What is an insoluble substance?
A substance that does not dissolve
A tool that is good for measuring and can be heated
What is a beaker
What does the law of conservation of matter state?
Matter can not be created nor destroyed only changed in form.
What useful information does the atomic number tell you?
How many protons are in one atom
Does a cation or a anion go first when naming?
The cation goes first
What are molecular covalent bonds made of?
Nonmetal atoms
Must have volume and mass
What is matter
What is a chemical formula and what does it tell you?
A set of chemical symbols showing the elements in a compound and it tells you how much of each element is in the compound
What information do you get from a Isotopic symbol?
Atomic mass and atomic number
What is it called when one or more electrons transfer from one atom to another causing magnetic attraction?
Iconic Bond
In the octet rule, does it state that valence electrons or core electrons have to add up to eight?
Valence electrons
A number which indicates how much "stuff" the object contains
What is mass
Describe how reactivity changes as you go down group 1A
The reactivity increases
How can you find the amount of neutrons with the mass and number of protons?
Subtract the number of protons from the mass
What is responsible for the colors of a flame during a flame test?
The metal atom is responsible for the colors during a flame test
Would the substance potassium bromide, KBr dissolve in water?
Yes KBr would dissolve in water
A curve formed by a liquid in a container
What is meniscus
If a substance weighs four ounces then goes through a chemical change how much will it weigh after?
It will weigh four ounces because matter cannot be created or destroyed
Calculate the mass of a substance with 47 protons and 52 neutrons
The mass is 99
If Ca has a charge of +2 what must F's charge be to follow the rule of zero charge?
F must have a charge of -2
How would a substance smell that has O double bonded to a c, bonded to a o, bonded to an H in it's structural formula smell?
It would smell putrid
