1. matter is the substance of which every physical object in the universe is made up of; matter is everything that takes up space and has mass.
2. matter is made up of atoms
3. no, you cannot see every particle within matter.
Date: 03.22.13
1. atomic number: 4, the number of protons
2. atomic mass: 9, added the protons and neutrons
3. element: beryllium, based off of the atomic number
4. protons: 4, positive charge
5. neutrons: 5, no charge
6. electrons: 4, negative charge
Date: 3/25/13
atomic number: 9
atomic mass: 19
name of the element: Fluorine
no charge because protons and electrons are equal.
