Chemistry A - Unit 2 - Ionic Compounds and Metals
What is the chemical formula for the chemical magnesium nitride? The chemical formula for magnesium nitride is Mg N.
3/2
Which diagram shows the correct way to represent an ionic compound of magnesium oxide?
Mg (+2) O (-2)
What is the chemical formula of magnesium bromide?
MgBr2
Which characteristic is typical of metals?
They are malleable.
In metallic bonding, ( ) move freely between neighboring atoms. Metals are ductile because the forces that hold their atoms together are ( ).
electrons/independent of the arrangements of atoms
A metal atom loses electrons from its outermost energy level and acquires a ( ) charge. These electrons join a nonmetal atom. The ionic compound formed because of this transfer of electrons is electrically ( ).
positive/neutral
What is the chemical name of this compound? Na2S
sodium sulfide
Complete the paragraph about the formation of sodium phosphide. Electrons are transferred from atoms of ( ) to atoms of ( ). This transfer makes the sodium atoms ( ) and the phosphorus atoms ( ). As a result, the sodium and phosphorus atoms strongly ( ) each other.
sodium/phosphorous/positive/negative/attract
It is difficult to break the ionic bonds in a compound because of the ( ). Ionic compounds are solid at room temperature because they have ( ).
strong attraction between ions/high melting points
What makes metals, in particular, good conductors of electricity?
the ability of electrons to flow throughout the metal
