It is aluminium as it’s in the 13th group, which mean it has 3 valence electrons
Answer:
By losing an electron
Explanation:
Electrons have a negative charge. So, losing one would give an element a more positive charge. You can usually find a hydrogen ion (H+) in substances like acids.
The Periodic Law states that the physical and chemical properties of the elements recur in a systematic and predictable way. When the elements are arranged in order of increasing atomic number. Many of the properties recur at intervals.
Group I and Group II have the same number of outermost electrons as you go down each group but the shells increase therefore as you go downward it becomes much easier to remove electrons because of its wide radius however group 7 and 6 have seven and six electrons in their outermost shell respectively. Therefore down the group it is much easier to attract electrons and across the period it is much harder because the number of electrons on the outermost shell increase
