Explanation:
All molecules of a compound have the same properties. ... All molecules of a compound have one type of atom.
Jeez, they r both true.....go with A. or C.
Hope this helps!

is it ok na I hope this answers are ok
Answer:
Electrons
Explanation:
"This free-floating collection of electrons gives metals many of their unique properties, and is sometimes called a “sea of electrons,”

Answer:
Because both compounds (CaCl2 and CaBr2) contain elements (bromine and chlorine) from the same group (group 7)
Explanation:
Elements are organized into groups on the periodic table based on the number of valence electrons contained in their outermost shell. These elements in the same group i.e. same number of valence electrons, will behave in a similar manner chemically.
CaCl2 and CaBr2 are two compounds that contains elements (Chlorine and Bromine) from the same group, which is group 7. Elements in group 7 are called HALOGENS and have 7 valence electrons in their outermost shell.
Bromine (Br) and Chorine (Cl) are responsible for the similarity in the properties of CaCl2 and CaBr2 because the Chlorine and Bromine contained in them will cause them to react similarly and behave similarly in the presence of other compounds.
