Valence and Chemical Bonding
Metallic Bonds
Covalent Bonds
Ionic Bonds
RANDOM
100
They are in the outermost cloud of an atom.
What are valence electrons?
100
These bonds form in metals.
What is a metallic bond?
100
They bond by sharing electrons.
What is a covalent bond?
100
It is this when it gains an electron.
What is a negative ion?
100
This is the name of our galaxy.
What is the Milky Way?
200
This is what hold atoms together.
What is a chemical bond?
200
How is a metallic bond formed? (answer not in form of a question.)
They are formed by the attraction between positive metal ions and the electrons in the metal.
200
Covalent bonds have low melting and boiling points and they are brittle in solid state.
What are the properties of covalent bonds?
200
It is this when it loses an electron.
What is a positive electron?
200
Who was our first president? (answer not in form of a question.)
George Washington.
300
How can you tell if an atom will bond or not. (answer not in form of a question.)
You can tell by looking at their valence electrons.
300
Why can electrons in metals move around? (answer not in form of a question.)
Metallic bonds squeeze many metals close to one another so their outermost energy levels overlap.
300
Covalently bonded atoms form this.
What is a molecule?
300
They are brittle, highly soluble, and have high melting and boiling points.
What are the properties of Ionic compounds?
300
What is the formula for density? (answer not in form of a question.)
Mass/Volume.
400
How do chemical bonds form? (answer not in form of a question.)
They form when atoms combine to form new substances.
400
What are some of metals properties? (answer not in form of a question.)
Metals are good conductors of heat and electricity, malleable, and ductile.
400
You use this to help you with covalent bonds.
What is an electron-dot diagram?
400
Ions that make an ionic compound are bonded in a repeating 3-D pattern.
What is a crystal lattice?
400
Where is the sun's energy produced? (answer not in form of a question.)
In the core.
500
If you do not know it's valence then how can you find out? (answer not in form of a question.)
By using the periodic table!
500
Why can metals bend? (answer not in form of a question.)
Metallic bonds occur in many directions.
500
What is the smallest particle of a covalently bonded compound that can be divided but still be the same compound? (answer not in form of a question.)
A molecule.
500
This is needed to remove electrons from metal atoms and is released when nonmetal atoms gain electrons.
What is energy?
500
How are stars formed? (answer not in form of a question.)
They are formed by gas and dust that are pulled into a sphere by gravity.
