Unit 2 Ūnderstanding Matter

In the study of matter, several foundational concepts are critical. Matter itself is defined by its mass and occupies space, with distinctions made between mass and weight. Mass refers to the amount of matter in an object, while weight is the force exerted by gravity on that object.

Unit 2 Understanding Matter

Atomic Mass/Structure

Two Types of Ion
- Anions = Negative
- Cations = Positive
What is an Isotope: Isotopes same element (atoms) with a different atomic mass (different number of neutrons)
PROTONS + ELECTRONS
ATOM IS NOT A CIRCLE (ALWAYS MOVING)
Number of Neutrons = THE ATOMIC MASS
Atomic Structure
PROTONS + POSITIVE CHARGE
ELECTRONS - NEGATIVE CHARGE
NEUTRONS_ NEUTRAL CHARGE
Atomic Number: number of protons
Hydrogen: ONLY HAS ELECTRONS AND PROTONS
ATOMIC MASS: is the equal number of protons and neutrons
