What is the chemical formula for water?
100
The amount of electrons in the outermost cloud.
What are valence electrons?
100
When valence electrons are transferred from one atom to another.
What is an ionic bond?
100
When atoms share one or more pairs of electrons.
When do covalent bonds form?
100
The joining of atoms to make new substances.
What is chemical bonding?
200
By subtracting 10.
How can you tell how many valence electrons a group has?
200
To get positive ions, you have to take away the electrons. To get negative electrons, you have to lose electrons.
How do you get positive and negative ions?
200
A bond formed by the attraction between positively charged metal ions and the electrons around the ions.
What is a metallic bond?
200
Ionic, covalent, and metallic.
What are the 3 types of bonds?
300
Makes 2 bonds
How many bonds does oxygen make?
300
True.
Atoms will steal/borrow/share valence electrons in order to gain a full outer cloud. True or False?
300
Positive charge is a metal and Negative charge is a nonmetal.
What subtances are in an ionic bond?
300
Its usually made of two or more definite ratio.
What is a molecule?
300
The valence electrons
What does the bonding depend on?
400
Makes 3 bonds
How many bonds does nitrogen make?
400
By sharing two electrons with or gaining two electrons from other atoms.
How can Sulfur gain a full outer cloud?
400
Has a strong bond.
Is an ionic bond weak or strong?
400
A model that shows only the valence electrons. It can help you predict how atoms might bond.
What is an electron-dot diagram and what is it used for?
400
Hydrogen, oxygen, nitrogen, carbon. Hydrogen has 1 bond, oxygen has 2, nitrogen has 3, carbon has 4. The bonds are in the order of the letter.
What is HONC?
500
Makes 4 bond
How many bonds does carbon make?
500
It can lose two electrons instead of gaining 6.
If Magnesium has two valence electrons, what can it do to gain a full outer cloud?
500
When 2 electrical charges attract.
What is an electrostatic attraction?
500
Has a weak bond.
