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).

In a geological isochron, SR stands for "slop ratio" and RB stands for "ratio of initial isotopes." SR represents the slope of the isochron line, which gives information about the age of the sample. RB refers to the initial isotopic composition of the sample, which helps in interpreting the geological history and processes.

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 the oxide formula for Rb?
Since Rb forms a 1+ ion the formula for rubidium oxide is Rb2O.
How an isochron map of the ocean floor supports the theory of seafoor spreading?
An isochron map of the ocean floor shows symmetric patterns of magnetic stripes on either side of a mid-ocean ridge. These stripes result from the alternating magnetic properties of oceanic crust formed at the ridge. The consistent pattern of magnetic stripes and their symmetrical distribution on both sides of a mid-ocean ridge provide evidence for seafloor spreading, where new oceanic crust is continuously being created at the ridge.
Explain how an isochron map of the ocean floor supports the theory of seafloor spreading?
An isochron map shows the age of the ocean floor, with younger rocks closer to the mid-ocean ridge and older rocks further away. This pattern supports the theory of seafloor spreading as it provides evidence of new oceanic crust being formed at the mid-ocean ridge, pushing older crust away on both sides. The symmetric patterns on either side of the mid-ocean ridge indicate continuous movement and spreading of the seafloor.
What is another name for geological seams?
Another name for geological seams is geological strata or rock layers.
What atomic radius is larger Rb or Sr?
The atomic radius of Sr (Strontium) is larger than that of Rb (Rubidium). This is because atomic radius generally increases down a group in the periodic table, and Sr is located below Rb in the same group.
Who won the Heisman Trophy in 1939?
1939 Nile Kinnick Iowa RB Sr.
When do you use Rb- Sr?
to date Volcanics and older than a few million years.
Who won the Heisman Trophy in 1935?
1935 Jay Berwanger Chicago RB Sr.
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?
The energy sublevel being filled by the elements Rb (rubidium) to Sr (strontium) is the 5s sublevel. These elements are in the fifth period of the periodic table, and in period 5, the s sublevel starts to fill up with electrons.
What are some alkali?
Li, Na, K, Rb, Cs, Fr, Be, Mg, Ca, Sr, Ba, Ra.
What is isochron slope 0.0077 in years?
.540
If the isochron slope is 0.0077 what is the age in millions of years when first evidence of abundant fossils?
If the isochron slope is 0.0077, the age in millions of years when the first evidence of abundant fossils would be around 129 million years (1/0.0077). This calculation assumes a linear relationship between the isochron slope and time.
A map in which rocks of similar age are colored the same is called a?
isochron :)
If the isochron slope is 0.0362 when does the Proterozoic Era begins?
2500 m
What do isochron maps of the seafloor indicate?
oldest near ocean ridges
