a can be ionic because of the formula
Answer:it dissolves and evaporates
Explanation:
The answer to this problem is E
Answer:
B Fluorine is the most reactive because it has 7 electrons in the outer shell.
Explanation:
The valid conclusion about the reactivity of the elements is that fluorine is the most reactive because it has 7 electrons in the outer shell.
- Reactivity of elements is in a bid to attain a stable configuration of their atoms.
- Fluorine belongs to group 7 on the periodic table.
- To complete its octet, it requires just one electron.
- This makes it very reactive
- On getting an electron, it becomes like the nearest noble gas, Neon.
