Whats is the definition of Chemical Bond?
The force of attraction between holds the atoms together.
100
What is an Ion?
An ion is a charged particle that forms when a atom or a group of atoms gain or loses one or more electrons.
100
What is Ionic Bonds?
The attractive force between oppositely charged ions, which form when electrons are transferred from one atom to another.
100
What are Covalent Bonds?
It is a bond that is formed when atoms share electrons.
100
What is a Metallic Bond?
A bond that is formed by the attraction between positively charged metal ions and the electrons around them.
200
What do the atoms want?
They want their outer cloud to be full.
200
How are Positive Ions formed?
They are formed when atoms pull electrons away from other atoms.
200
When they are bonded what is that called?
Crystal Lattice
200
What are examples of a covalent bond?
Water, Sugar, and Carbon Dioxide.
200
Why can metal be bent or shaped?
They can be shaped in different ways because of the presence of metallic bonds.
300
What does chemical bonds depend on?
They depend on the number of valence electrons.
300
How are Negative Ions formed?
Negative ions are formed when the atoms gain more electrons.
300
Why is table salt an ionic compound?
Because table salt is made up of three-dimensional pattern.
300
What is the definition of a Molecule?
A group of atoms held together by covalent bonds.
300
What are properties of metals?
You can reshape them and you can bend them without breaking them.
400
How many valence electrons does group 2 have?
Group 2 has 2 valence electrons.
400
What are Ionic Compounds?
The ions that has bonded, they move in a repeating three-dimensional pattern.
400
What is Crystal Lattice?
The regular pattern in which a crystal is arranged.
400
What do the atoms become when they bond?
They become molecules.
400
How do electrons move throughout metals?`
They move in all different directions.
500
How many chemical bonds are there? What are the types of bonds?
3. Ionic, Covalent, and Metallic.
500
What is a property of an Ionic Compound?
They become brittle at room tempature.
500
What is one way to represent atoms and molecules?
Dot-Diagrams.
500
Why doesn't the metal break when you pound it down?`
Because the positively charged ions repel on one another.
