Answer:
Malachite green has highest percentage of copper.
Explanation:
Azurite: 
Molar mass of Azurite = M = 344.67 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Azurite :
The percentage of copper in an azurite is 55.31%.
Malachite: 
Molar mass of Malachite = M = 221.12 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Malachite:
The percentage of copper in an malachite is 57.48%.
Like terms in algebra are terms that have the same variables and power. Constants contain only numbers, we call them constants because their values don't change. Coefficients are the numbers in front of the variable ex: 5y in that expression 5 is the coefficient. So in the expression 2+3a+9a there is one constant which is 2 the likes terms are 3a and 9a because they have the same variable. And the coefficients are 3 and 9 because they are in front of the variable.
Answer:
they gain the few electrons they need to form full octets
