Ionic Bonds
Covalent Bonds
Metallic Bonds
Ions
Chemical Bonds
100
Positive and negative . or metal and nonmetal .
How do Ionic Bonds form ?
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
A charged particle that forms when an atom or group of atoms gains one more electron .
What is an ion ?
100
An interaction that holds atoms or ions together.
What is a chemical bond ?
200
Less negative .
What do you call a positive atom has lost electrons ?
200
between 2 nonmetals
How do Covalent Bonds form ?
200
The electrons move around freely .
How do electrons more around in Metallic bonds ?
200
Atoms pull electrons away from other atoms .
During chemical changes , ionic bonds form when ?
200
The electrons are shared, gained, or lost .
What happens when chemical bonds are formed ?
300
More negative .
What do you call a negative atom that has gained electrons ?
300
Molecules .
Substances that have covalent bonds consist of what particles ?
300
electrical conductivity , malleability, and ductility .
Metallic bonding gives metals their particular properties . Those properties include ?
300
The metal atoms tend to lose these valence electrons and form positive ions .
What happens when metal atoms bond with other atoms ?
300
A full outer ring.
What do atoms want when their bonding ?
400
They form so that the outermost energy levels of the atoms in the bonds are filled .
Why do Ionic bond form ?
400
To use a dot diagram . ( dot diagram is a modle that shows only the valence electrons in an atom. )
What is one way to represent atoms and molecules ?
400
Conduct electric current .
Metallic Bonding allows metals to ?
400
Energy is needed to overcome the attraction of the electrons to the protons in the nucleus .
What happens when an atoms loses electrons ?
400
Ionic, covalent, and metallic bonds .
What are the 3 types of bonds ?
500
The number of the electrons in the atom equals the number of protons .
In Ionic Bonds how is an atom neutral ?
500
A large amount of energy is needed for either atoms to lose an electron .
What happens when two atoms of nonmetals bond ?
500
Ductility - the ability to be drawn into wires Malleability - the ability to be rolled or pounded
What two properties can describe a metal's ability to be reshaped ?
500
Because the energy needed to remove electrons from their atoms is so small .
Why do the elements in groups 1 and 2 react very easily ?
500
They have 10 fewer valence electrons than their group number . Expect for helium atoms have only 2 valence electrons .
How many valence electrons does group 13-18 have ?
