Nature of Matter

All matter is made up of _______?

• Energy

• Cells

• Atoms

• Light

Which types of matter is made up of MORE than one type of atom, bonding to create something new?

• Element

• Mixture

• Compound

• Atom

Which type of matter is made up of ONLY one type of atom?

• Element

• Mixture

• Compound

• Atom

The atom is made up of:

• Protons: + charge and found in the nucleus
  Electrons: - charge and are found in the nucleus
  Neutrons: no charge and are circling the outside of the nucleus
• Protons: + charge and are circling the outside of the nucleus
  Electrons: no charge and are in the nucleus
  Neutrons: - charge and are found in the nucleus
  electrons 
• Protons: + charge and are found in the nucleus
  Electrons: - charge and are found circling the nucleus
  Neutrons: no charge and are found in the nucleus
• Protons: + charge and are found in the nucleus
  Electrons: no charge and are found circling the nucleus
  Neutrons: no charge and are found in the nucleus

Examine the following atom which consists of 12 protons, 12 neutrons, and 10 electrons.  Choose its designation:

• isotope
• ion
• neutral atom
• compound

Isotopes of an element differ in the amount of ___ that they have.

• electrons

• neutrons

• nuclei

• protons

Identify the type of chemical bond. 

• ionic
• hydrogen
• James
• covalent

When some electrons are not shared equally in a covalent bond, it can create a positive or negative charge which might attract other molecules.  This is a weak force.  Geckos make use of this force to walk on ceilings.  The force is called:

• Atomic Force
• van der Waals Force
• Nuclear Force
• Ionic Force

The scale which measures how acidic or basic a substance is, is called the ____ scale.  It runs from ___ to ____.

• pH: 0-14
• pH: 0-7
• Barometric: 1-10
• Fish: 1-4

An acid results from more__ ions in solution, compared to pure water.  

• hydroxide
• hydrogen
• hydrogen peroxide
• helium
