Answer:
If you meant the Periodic Table it's the alkaline-earth metal
beryllium (Be) 
magnesium (Mg)
calcium (Ca)
strontium (Sr)
barium (Ba)
radium (Ra)
Explanation:
 
        
             
        
        
        
True because heat energy moves to the warmer areas.
        
                    
             
        
        
        
Your answer would be total number of atoms! This is because when you have these equations which require total number of atoms. 
        
                    
             
        
        
        
Answer:
The magnitude of acceleration is reduced.
Explanation:
Force is defined as push or pull
The force is said to be<em> balance force  </em>if the force are equal in size but opposite in direction. ie the object does not move or move with constant speed.
The force are to be<em> unbalanced force </em>if the force cause change in motion. ie the object has force greater than zero and has acceleration.
According to <em>Newton second law of motion </em>, acceleration depends on force acting on the object and mass of object.
      F=ma
      a=
When unbalanced force act on the mass of object it reduces magnitude of acceleration without changing the direction.
