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

Matter

What are the different Types of Matter?

What are the different States of Matter?

How is are mass and weight different?

What is Matter?

Main topic

Subtopic
