Rank these elements in terms of increasing atomic radius?
In terms of atomic radius, the sequence would be oxygen, carbon (both period 2), magnesium (period 3), rubidium (period 4), and cesium (period 5). Note that order by periods is not absolute: in each period, the elements toward the far left side have the largest radii. For example, the radius for lithium in period 2 is larger than almost all of the elements in periods 3 and 4. *Numerically, the elements O, C, Mg, Rb, and Cs have respective radii of about 60, 70, 150, 235, and 260 picometers.
What is the balanced equation for rubidium-87 turns into strontium-87?
this is an example of β radiation, n -> p + e Rb-87 -> Sr-87 + e (rem to write atomic numbers in, Rb is 37 and Sr is 38) The halflife 87Rb is 4,88.1010 years.
Which energy sublevel is being filled by the elements Rb to Sr?
5s
What is the relationship between the atomic number of an element and its atomic radius from the graph of your lab report?
Atomic number = number of protons Atomic mass number = number of protons + number of neutrons Relative mass number = the weighted average mass numbers of the naturally occurring isotopes as compared to C-12 If you delete the atomic number from the mass number you get the number of neutrons. The atomic number is the number of protons and electrons. (They are both the same number.)
Which elements atomic weight is 107.8682?
In the periodic table, the element with 107.87 as its atomic mass is silver (Ag)

What is the electron configuration for element kr?
The lowest atomic number ion is Se^2-. The highest atomic number ion is Sr^2+. The ones in the middle are NOT Br^- or Rb^+. However, I do not know what the correct answer for those two is.
What is SR and RB in geological isochron?
SR is Strontium and RB is Rubidium. In Rubidium-strontium dating they are normally plotted as the ratio of 87Sr/86Sr against 87Rb/86Sr on the graph (isochron).
Which energy sublevel is being filled by the elements Rb to Sr?
5s
