So… What’s the difference between elements, compounds and and mixtures?
Well…
Elements are a pure substance that make up only one kind of atom. You can’t break it down chemically (like gold).
Compounds are pure substances made of two or more atoms that are bonded together chemically (like water).
Mixtures are two or more substances (not pure) that are not bonded together. It can be broken down (i.e. salt water, you can separate the salt from the water).
What’s an atom?
The humble atom is the building block of matter. The smallest unit of an element (that still has all the element’s properties) (there can be oxygen, gold, nitrogen atoms). Three parts to an atom- protons (positive charge) neutrons (no charge) and electrons (negative charge).
International symbols for common elements are used because they are common to every language.
This is true. Fe means iron
everywhere.
What’s the abbreviation for an element called?
A symbol.
How are element symbols structured?
First letter is always in capital letters. If there’s any other
letters, they are lower case.
Where will you find each kind of tron or ton in the atom? How do you draw it all?
Neutrons and protons sit in the nucleus. Draw the neutrons next to the protons, and put a plus on the protons to signify what they are.
Electrons belong in the shell of the atom, orbiting the nucleus. Draw minuses on the electrons.
