Scientific laws are <u>internally consistent</u>, compatible with evidence, and are <u>testable against a wide range of phenomenon</u>. However, <u>they can be reviewed</u> as more evidences emerge that have not been known before.
Their outermost shell has the maximum number of electrons it can hold.
Elements only react with each other to gain electrons to complete their outermost shell. Since noble gases already have a complete outer shell, they're usually inactive.
