Unit 3 Atoms, Chemical Bonding and pH scale

the central region of an atom where its neutrons and protons are is its 

• nucleus 
• electron cloud
• core 
• center 

an atom with atomic number 6 would have how many protons 

• 6
• 12
• 3
• cannot be determined 

Particles in an atom that are neutral and have no charge are 

• negatrons 
• electrons 
• neutrons 
• protons 

An atoms overall charge is generally

• positive 
• depends on its mood 
• neutral 
• negative 

Which of these is the electron?

• A
• B
• C
• D

Which number here is my atomic number?

• 5
• 10.811

Ionic Bonding involves...

• The transfer of protons
• The transfer of nuetrons 
• The transfer of electrons
• None Of the above

What is an ionic bond?

• When two ions are held to each other by attraction of between the opposite charges
• When ions seperate by force
• None of the above

Covalent compounds

• Share electrons
• transfer electrons
• contain a sea of electrons
• conduct electricity

Two or more atoms chemically joined are called...

• atoms
• ionics
• covalents
• compounds
