Ionic Bonds
Covalent Bonds
Metallic Bonds
Valence Electrons
Positive and Negative Ions
100
An positive ion!
What is it called when an ion has more protons than electrons?
100
A bond formed when atoms share one or more pairs of electrons!
What is a covalent bond?
100
A bond formed by the attraction between positively charged metal ions and the electrons around them!
What is a metallic bond?
100
Atoms of an each element have the same number!
Valence electrons have the same number of?
100
The atom would become positive.
What happens if an atom loses electrons?
200
A charged particle that forms when an atom or group of atoms gains or losses one or more electrons!!
What is an ion?
200
An electron-dot diagram!!
What diagram do you draw to show the covalent bonding between electrons?
200
They are formed when the metal atoms lose electrons!!
When are positively charged metal ions formed?
200
The outer electron!
What is a valence electron?
200
If an atoms has 13 protons and 13 electrons then what would its charge be?
0 charge
300
It changes the number of electrons!!!
What does a transfer of electrons between atoms do?
300
The smallest particle into which a covalently bonded compound can be divided and still be the same compound!!!
What is a molecule?
300
The metallic bonds allow the metal to!!!
Why can metals be reshaped?
300
You can use the periodic table to find it.
What can you use to find an element's valence electron?
300
What is the charge if an atom has 7 protons and 8 electrons?
Negative charge.
400
The attractive force between oppositely charged ions, which form when electrons are transferred from one atom to another!!!!
What is an ionic bond?
400
At least two covalently bonded atoms!!!!
What are molecules composed of?
400
Conducting electric current, reshaping metals, and bending without breaking!!!!
What are some properties of metals?
400
If they don't have a full outer cloud!
How can atoms bond?
400
Atoms gain electrons from other atoms.
What happens during chemical changes?
500
When valence electrons are transferred from one atom to another atom!!!!!
When do ionic bonds form?
500
Diatomic molecules!!!!!
What type of molecules are the simplest?
500
The atoms inside the metal are so close they overlap so that bonds easily form. These metallic bonds extend throughout the metal in all directions.
Why can valence electrons move throughout the metal?
500
You can by gaining, losing, or sharing electrons!!
What are the ways an atom can get a full outer cloud?
500
Forms when atoms pull electrons away from other atoms.
