Hi! where are the options?
Answer (3) is the most correct, although (2) is not to be ignored. (3) states the most abundant isotope Ti's average mass, which is certainly true. (2) is the total mass of all protons, neutrons, and electrons in an atom of Ti, which is true but has to be more specific in order to pinpoint exactly the 47.88 amu. (4) is incorrect because it is not of all the naturally occurring isotopes of Ti. (1) is incorrect because they forgot electrons.
Because its in group one....which only lose or gain electrons.....thus it will only have oneelectron to fulfill its octect rule
D. because matter is uniform through and cannot be separated into other substances by physical means.
The coefficient in a chemical formula represents the amount of each chemical present. The amount of a substance is measured in moles.
