Atomic Structure Visit

Average Atomic Mass Practice

Subatomic Particles and Isotopes. Subatomic Particles Protons- Positively Charged Protons- Positively Charged Located in the nucleus Located in the nucleus.

Periodic Table of Elements. Element An element is a substance that is made up of ONE kind of atom only. e.g. Carbon.

PRACTICE DRAWING ATOMS. DRAWING ATOMS RULES PROTONS = Atomic number ELECTRONS = Atomic number NEUTRONS = mass number – atomic number 1 st level can hold.

HOW MANY PROTONS, ELECTRONS, AND NEUTRONS ARE IN AN ATOM?

11 12 Sodium Atomic number = Mass Number = p+p+ n protons & neutrons 12 neutrons In a neutral sodium atom the number of protons (11)

Atomic Structure. Rules Of Atomic Structure 1.The Number of electrons = number of protons 2.Atomic Number = the number of protons/electrons 3.Atomic Mass.

Atoms Is made Up of 2 Parts: The Nucleus: 1. Protons 2. Neutrons The Rings: 1. Electrons.

Reading the Periodic Table. What does Atomic Mass tell us?

What is the smallest unit of matter? An atom What is an atom made of? Subatomic particles protons (p + ) – positive charge neutrons (n) – no charge.

Atomic Structure.

Put a different element name on each card, along with its symbol, number of protons and number of electrons. Metals on 1 colour, others on other What makes.

Challenge #1 T. Trimpe 2008

Atomic Structure Test Review 166 point total. 1.The atomic number is the number of protons. 2. The mass number is the number of protons and neutrons.

The Atom.  An atom is the smallest particle of matter that still has the same properties of that element. What is an atom? Atoms = Building Blocks Na.

Atomic Number The number of protons in an atom Also, the number of electrons in a neutral atom.

Isotopic Abundance Pages Thinking question Why are there decimal places for atomic masses on the periodic table if protons and neutrons have amu.

Parts of an Atom Proton, Neutron & Electron Proton (p+)

2. What are isotopes? Use two particles from the table above to illustrate your answer. (3 marks) 17 O & 18 O (1) Same Atomic mass / number of protons.

Theories of the Atom. Ernest Rutherford (Gold Foil Experiment) Discovered that atoms have a positively charged central mass called the nucleus Hypothesis:

Average Atomic Mass Practice

Atomic number = number of protons # protons = # electrons IN NEUTRAL ATOMS.

Atomic Structure. It used to be thought that atoms were small indivisible particles. It was thought that the only difference between the atoms of one.
