Compounds can be formed from two or more metals. when the difference in electronegativity between the metals is very large, these compounds may be bonded by a mixture of metallic bonds and bonds. a. lonic b. van der waals c covalent o d. hydrogen

a) Ionic

Explanation:

Natural and artificial compounds can be formed from two or more metals.

If the difference in electronegativity between the metals is very large, these compounds may be bonded by a mixture of chemical bonds. Those can be metallic bonds and other types of bonds.

According to the electronegativity difference between two components, if it is equal or higher than 1.7 they are classified as ionic bonding. In this sense, if we have two metals with a very large difference of electronegativity. Let's suppose higher than 1.7, they will form an ionic bonding.

Finally, Answer is a) Ionic bonding when the difference in electronegativity is very large.  

i think it is true since you can test the answer and can use observations to complete it.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
