Test Flashcards
What is ionic bonding?
Ionic bonding involves the transfer of electrons between a metal and a non-metal.
What do both sides achieve after electron transfer in ionic bonding?
Both sides usually achieve full outer shells.
What are ions?
Ions are formed after electrons transfer between atoms.
What happens to a metal atom during ionic bonding?
The metal loses an electron to become positively charged (cation).
What happens to a non-metal atom during ionic bonding?
The non-metal gains an electron to become negatively charged (anion).
What charge does sodium (Na) form when it loses an electron?
Na forms a +1 charge.
What charge do Group 1 elements form when they lose an electron?
Group 1 elements lose an electron to form +1 ions.
What charge do Group 2 elements form when they lose an electron?
Group 2 elements lose an electron to form +2 ions.
What charge do Group 7 elements form when they gain an electron?
Group 7 elements gain an electron to form -1 ions.
What charge do Group 6 elements form when they gain an electron?
Group 6 elements gain an electron to form -2 ions.
