100
A representation of the valence electrons in an atom, using dots.
What is electron dot diagram?
100
these are described as:
loosely held by the nucleus
shown on electron dot diagrams
transfered or shared in bonding
What are valence electrons?
100
An atom or group of atoms that has an electric charge.
What is an ion?
100
A covalent bond is called this if the atoms equally share one or more pairs of electrons.
What is nonpolar?
100
An attraction between a positive metal ion and the electrons surrounding it.
What is metalic bond?
200
Ionic compounds typically have these properties. (3)
What is high melting point and boiling point, and ability to conduct electricity when melted or dissolved in water?
200
the number of these remains the same from top to bottom in a group in the periodic table.
What is valence electrons?
200
These ions are composed of more than one atom.
What are polyatomic ions?
200
A molecule in which the the electrons are shared unequally between two atoms is this.
What is polar?
200
Metals have this property, which is the ability to be hammered into sheets
What is malleable?
300
A chemical bond formed when atoms share three pairs of electrons.
What is a triple bond?
300
Elements in Group 17, the halogen family, are very reactive because their atoms have this many valence electrons.
What is seven?
300
This type of ion is formed when an atom loses an electron.
What is a positive ion?
300
In a double bond, this many electrons are shared.
What is four?
300
This is a mixture of two or more elements, one of which is a metal, that has the properties of a metal.
What is an alloy?
400
When writing a chemical formula for an ionic compound, write it this way.
What is positive ion first, negative ion second, with subscripts to balance the charges?
400
Most atoms become less reactive after achieving this number of valence electrons when bonding
What is eight?
400
This is formed when an atom gains an electron.
What is a negatively charged ion?
400
A neutral group of atoms joined by covalent bonds is called this.
What is a molecule.
400
Solid metals can be described as this type of metal ion surrounded by freely moving valence electrons.
What is a positive metal ions surrounded by freely moving valence electrons?
500
An attraction between a positive metal ion and the electrons surrounding it.
What is a metallic bond?
500
Represented by this picture
What is electron dot diagrams
500
When a compounds written like this:
H2O, MgCl2, NaCl
What is chemical formula?
500
A bond represented by this model of CO2
What is a nonpolar bond?
500
The properties of metals can be described by the ______________ and _____________ among metal ions.
What is structure and bonding?
