Intro to Chemistry
SOL 2
Matter is anything that has _______________ and takes up
_______
It is made up of atoms which are the _____________ units that
anything can be broken down to and still be the
____________________
Atoms are made of 3 main parts
Protons
- ___________ in __________
Neutrons
Electrons
- __________ in __________
- __________ in __________
The periodic table places elements in order based on how reactive
they are grouping them by similarities. This is how we determine the
number of protons, neutrons, and electrons.
We must first identify (label each on the carbon below)
Atomic #: the whole number/the smaller number
Symbol: typically the latinized abbreviation of element
Atomic Mass: this is the larger number
APE MAN
Atomic # = gives us Protons and Electrons
Remember this Acronym-
Mass – Atomic # = Neutrons
Isotopes –
Element: composed of a ____________________ Ex:
Lithium
Sulfur
Compound: two or more ____________ atoms chemically bonded
together
Ex:
Molecule: two or more of the ____________ or ______________
elements chemically bonded together Ex.
Mixture: two or more substances that are __________ chemically
bonded together Ex:
Drawing an element
The 1st shell holds
The 2nd shell holds
The 3rd shell holds
For this class we will stick with _____ in the next orbit as well.
Ionic Bond
Sodium
