Ionic Bonding Flashcards
Bonding, Structure, and Properties of Matter (16 cards)
What happens when a metal and a non-metal react together?
The metal atom loses electrons to form a positively charged ion, and the non-metal gains these electrons to form a negatively charged ion.
What is the attraction between oppositely charged ions called?
Ionic bond.
What do dot and cross diagrams represent?
The arrangement of electrons in an atom or ion.
In sodium chloride (NaCl), what does the sodium atom give up?
Its outer electron.
What ion does the sodium atom become after losing its outer electron?
Na+ ion.
What does the chlorine atom do in the formation of NaCl?
Picks up the electron.
What ion does the chlorine atom become after gaining an electron?
Cl- ion.
Fill in the blank: The magnesium atom gives up its two outer electrons, becoming a _______ ion.
Mg2+
What ion does the oxygen atom become after gaining two electrons?
O2- ion.
In magnesium chloride (MgCl2), how many chlorine atoms pick up electrons?
Two chlorine atoms.
What do the two chlorine atoms become after gaining one electron each in magnesium chloride?
Two Cl- ions.
In sodium oxide (Na2O), how many sodium atoms give up their outer electrons?
Two sodium atoms.
What ion do the sodium atoms become after giving up their single outer electron?
Na+ ions.
What does the oxygen atom become after picking up the two electrons from sodium atoms?
O2- ion.
True or False: Dot and cross diagrams show the structure of ionic compounds.
False.
What information do dot and cross diagrams fail to show about ionic compounds?
The structure of the compound, the size of the ions, and how they’re arranged.
