John is studying for his Chemistry quiz. He took the notes below (in blue) about barium and iodine, which are known to form ionic bonds.
Barium, which is a metal, donates 2 electrons to iodine.
The individual barium atom becomes an ion with a negative 2 charge.
The bond between barium and iodine makes the atoms stable.
Barium and iodine attract each other.
Which best describes John's error?
John's error is that he mistakenly described the barium atom as becoming an ion with a negative 2 charge. Barium, being a metal, tends to donate electrons and become a positively charged ion, not a negatively charged ion.
a
Barium and iodine repel, not attract, each other.
b
The bond formed makes the atoms unstable, not stable.
c
The individual barium atom has a positive, not negative, 2 charge.
d
Barium is a metal, so it donates protons, not electrons.
