Jim uses an electric balance to measure the mass of a magnesium strip. If the strip has a mass of 6.10 g, how many moles of magnesium are in the strip?

a chemical reaction happens

explanation:

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

a electronegativity decreases beacuse the size of nucleus is bigger.
