Pretend that unbinilium has an atomic mass of 299.01 amu. It is a group 2A element. In the future, a local scientist reports that they have successfully synthesized 0.0295 moles of unbinilium. How many grams of unbinilium is this?

Do not enter units.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
