Metallic Bonds
100
These electrons have the highest energy level and are held most loosely.
What is a valence electron?
100
This group of elements are very reactive metals. They lose one valence electron.
What are Alkali metals/Group 1 metals?
100
An atom or group of atoms that has an electric charge.
What is an ion?
100
This is a neutral group of atoms joined by covalent bond.
What is molecule?
100
This is a mixture made of two or more elements, at least one of which is a metal.
What is an alloy?
200
This includes the symbol for the element surrounded by dots. The dots represent a valence electron.
What is the electron dot diagram?
200
This group of elements contains 3 valence electrons in its outermost shell/energy level.
What is Group 13/Boron Family?
200
The force of attraction between two oppositely (positively and negatively) charged ions.
What is an ionic bond?
200
Bonds that form between two nonmetal atoms usually share valence electrons.
What is a covalent bond?
300
Most atoms are more stable when they have this number of valence electrons.
What is 8/eight?
300
When a sodium atoms bonds with a chlorine atom. It forms a ionic compound that is written using what chemical formula.
What is NaCl?
300
When an atom gains an electron it get this type of electrical charge.
What is a negative charge?
300
A covalent bond in which electrons are shared unequally is known as this.
What is polar bond?
400
This is the number of valence electrons that aluminum has.
What is three/3?
400
These ions are made of atoms that act as a group that reacts as a unit.
What is a polyatomic ion?
400
This is a combination of symbols that shows the ratio of elements in a compound.
What is a chemical formula?
400
When atoms form bonds in which they share three pairs of electrons. They form this type of covalent bond.
What is a triple bond?
500
This is the force of attraction that holds two atoms together as a result of the rearrangement of electrons between them.
What is a chemical bond?
500
This is the formula for the compound aluminum fluoride.
What is AlF ?
500
In general, ionic compounds are hard, brittle solids with high melting points. When melted or dissolved in water, they conduct electric current.
What is properties of ionic compounds?
500
Molecular compounds generally have lower melting points and boiling points. They do not conduct electric current when melted or dissolved in water.
What is are properties of molecular compounds?
