100
What determines if the atom will bond with another?
valence electron
100
Ionic bonds form between a _____ ion and a ______ ion.
A positive and negative ion
100
When does a covalent bond form?
A covalent bond forms when atoms share electrons.
100

What is ionization energy?

The amount of energy it takes to remove an electron from an atom

200
What does an atom have to do to become a negatively charged ion?
gain electrons
200
How many valence electrons are in group 16?
6
200
Ionic bonds form between what classes of elements?
Metals and nonmetals
200
What class of elements does a covalent bond form between?
A covalent bond forms between nonmetals.
200

Which requires more ionization energy, Zn or Zr?

Zn

300
what is an ion
a charged atom
300
based on the number of valence electrons would elements in group 18 make bonds?
no
300

Why is ionic stronger than covalent bonds?

attraction

300

Why isn't covalent stronger than ionic bonds?

no attraction.

300

Why does ionization energy increase upwards on the periodic table?

If an element has a lower atomic number, it has fewer shells, so the electrons are closer to the nucleus, which means that the electrons are harder to remove from the atom.

400
Would two positive ions make bonds?Why?
No, because alike charges are not attracted to each other.
400
How many valence electrons does aluminum have?
3
400
A negatively charged atom gains electrons when it is bonded to another with an ionic bond, so the atom becomes more ________.
Negative
400

what do electrons do in a metal bond?

share the electron cloud.

400

Why do elements on the right of the periodic table require more ionization energy?

Elements on the right of the periodic table, have more valence electrons so they require a larger amount of energy to remove all the electrons

500
What is a Cation?
a positively charged ions
500
why wont elements in group 18 make bonds?
because their outer shell is full
500

What are qualities of substances that are bonded by ionic bonds?

They are hard, brittle, and have high melting points.

500
What are the qualities of a substance that is bonded by covalent bonds?
The qualities are low melting and boiling point, also they tend to be brittle when in a solid state.
