Chemical Classification Flashcards
In ionic bonding what happens to non metal to form negative ions?
They gain electrons
Solubility of ionic substances?
Many dissolve in water
An example of ionic bonding?
Sodium chloride
MP and BP of ionic substances?
High, solid at room temperature
When do ionic substances conduct electricity?
When molten or in a solution
How are bonds formed in simple MC
Atoms share electrons to get full outer shell.
Covalent bonds hold atoms together in molecules.
An example of simple MC
Water, oxygen
Strength of bonds between simple MC
Strong bonds between each molecule, weak forces holding the separate molecules together
Melting and boiling point of simple MC
Have low MP and BP
Liquids or gases at room temperature
Solubility of simple MC
Some dissolve in water
Do simple MC conduct electricity?
No
In ionic bonding what happens to metal atoms to form positive ions
They lose one or more electrons
Atoms share electrons to get a full outer shell. Covalent bonds hold billions of atoms together in giant structures.
What type of bond is this?
Giant molecular covalent bond
What’s an example of a GMC?
Quartz
What kind of bonds do GMCs have?
Strong
