Atoms, Bonding, and the Periodic Table
This group of elements can become stable by losing one valence electron
Alkali Metals (Group 1)
The charge on a Magnesium ion when it bonds with Oxygen
2+
This type of bond is formed when valence electrons are shared equally between atoms
Non-polar bond
Metals are able to conduct electric current because of these particles, which flow freely within a metal crystals.
Valence electrons
When an atom loses a valence electron, it becomes this:
A positive ion (positive)
With the exception of Helium, all the elements in this group are stable with 8 valence electrons in their outer shell
Noble Gases (Group 18)
The charge on a Fluoride ion when it bonds with Sodium
1-
The type of covalent bond found in a molecule of H2O
Polar Covalent Bond
Name four properties of Metals
Luster, Malleability, Ductility, Thermal Conductivity, Electrical Conductivity
Because of it's small atomic radius and lacking of one valence electron, this element is known to be the strongest on the periodic table
Fluorine
The number of electrons present in an electron dot diagram of Oxygen
6 valence electrons
The chemical formula for Calcium Oxide
CaO
Two double bonds are formed between carbon and two oxygen atoms, resulting in this non-polar molecule:
Carbon Dioxide (CO2)
These are homogenous mixtures of 2 or more metals, often combined in order to result in stronger, less reactive metals that can be used
Alloys
Name two properties of ionic crystals
High Melting Points, Electrical Conductivity when dissolved in water
This is the force of attraction that holds atoms together. Types of these include ionic bonds, covalent bonds, and metallic bonds.
Chemical Bond
The chemical formula for Aluminum Fluoride
AlF3
Name two properties of molecular compounds bonded covalently
Poor Electrical Conductivity, Low Melting/Boiling Points
These kinds of materials have no resistance to the flow of electric current, and can carry electric currents for long periods of time without losing energy as heat
Superconductors
Sterling Silver, an alloy often used in the production of jewelry, is usually composed of about 93% silver and 7% of this element
Copper
Because of this element's ability to chemically bond with 4 potential atoms, it is often found forming large chains of molecules, some of which are responsible for the development of life on Earth.
Carbon
The chemical formula for Aluminum Oxide
Al2O3
This type of bond is formed when 3 pairs of electrons are shared in a diatomic molecule of N2
Triple Covalent Bond
The group with the largest atomic radii
Alkali metals (Group 1)
The approximate melting point of halite, more commonly known as table salt, or sodium chloride.
800/801 degrees Celsius
