The table gives information about three elements represented by J, K and L.
| Element | Position in the periodic table | Number of electrons in the outer shell |
|---|---|---|
| J | Left side | 1 |
| K | Right side | 6 |
| L | Right side | 7 |
Compound 1 contains J and L.
Compound 2 contains K and L.
Which statement correctly compares the two compounds?
Compound 1 is ionic because an electron is transferred from J to L; compound 2 is molecular because K and L share electrons.
Compound 1 is molecular because J and L share electrons; compound 2 is ionic because electrons are transferred from K to L.
Both compounds are ionic because electrons are transferred to L from either J or K.
Compound 1 is ionic because an electron is transferred from L to J; compound 2 is molecular because K and L share electrons.
