Covalent and Ionic Bonds -Explain the difference between the two
Ionic bonds result when electrons are tranfered between atoms. Covalent bonds result when valence electrons are shared between atoms. You should be able to identify whether an ionic or covalent bond is being formed between atoms.

Atomic Structure of chalcogens:
All have 6 electrons on outer ring
where can halogens be found
All of the halogens can be found in the Earth's crust.
State 5-7 physical properties that all the salts all have in common. State a chemical property they have in common.
All the salts have a reaction when you put in the fire. They all have a acid-base-reaction, hyrochlic acid, and sodium hydroxide.They all are in the form of powders or gounded up substances.
Explain, using the diagram below, how an ionic bond is formed.
An ionic Bond is formed when an element has one electron on the third ring and it gives it to another element. However the element that gave the electron loses its third ring. Sodium hs one electron on its outer ring and chlorine has 7. Chlorine needs 8 in order to be full. Sodium gives that one electron to chlorine to make chloruine full. Sodium loses its outer ring and its new outer ring is full.
Protons and Electrons are equal to ______
Atomic #
how to find # of neutrons

what are atoms
Atoms are the basic units of matter and the defining structure of elements. Atoms are made up of three particles: protons, neutrons and electrons. not enegry
Why are there two rows at the bottom......Why are they there? What If the they were not at the bottom, what would the table would look like?
Because if you put lanthanides and actinides in to the Periodic Table like transition metals, the table will be way too wide. The two rows of elements present at the bottom of the periodic table are called the 4f series or lanthanoids and 5f or actanoids. They are also called inner transition elements.
