Chemistry help?
a. the newest inert gas
b. the new element with properties similar to those of the alkaline earth metals
c. the new element that will behave like the halogens
d. the new (nontransition) metal whose ion will have a +2 charge
e. the new element that will start period 8
Answer:
The question is difficult because it doesn't just ask you to locate information or define a term. Instead, it is asking you to use your knowledge of the periodic table and extend it to a new situation.
First, get out your Periodic Table. Find the element with atomic # 114 (it's under Pb in Group 14).
a) The questions says to assume scientists make a new inert gas with atomic # greater than 114. In which group do we find the inert gases (noble gases)? Group 18. Atomic # 115 would be located in Group 15, #116 in Group 16, #117 in Group 17, and #118 in group 18.
So the newest inert gas would have an atomic number of 118.
b) Alkaline Earth Metals are the Group 2 elements. Starting a new Period (period 8), fictional element #119 would be in Group 1, and #120 would be in Group 2.
The newest alkaline earth metal would have atomic #120.
Repeat this analysis for c-e.
Do you know Stephen Hawkings, maybe if you wrote to him he would help you. Is this a project that you have to do for school, sometimes it makes me mad when people want us to do their homework for them ! Do you know how long it would take me to give you all the answers for this, think about it !!
why would stephen hawking know about this, hes a physicist
a]118
b]120
c]117
d]120
e]119
