Abundance of boron in the universe?
Boron in the solar system: approx. 1.10-5 (atom mole fraction relative to silicon)
Is boron rare?
Boron is abundantEstimated Crustal Abundance: 1.0×101 milligrams per kilogramEstimated Oceanic Abundance: 4.44 milligrams per liter
A boron atom is made of?
The boron atom is made up of 5 electrons, 5 protons, and 6 neutrons. This element is low in abundance in both the solar system and the Earth's crust.
What is the relative abundance of lawrencium?
Lawrencium is an artificial element, not found in the nature.
The relative abundance of each isotope of an element determines its?
The relative abundance of each isotope of an element is used to determine its atomic mass. This is the weighted average of all naturally occurring isotopes.

If The average mass of a boron atom is 10.81 what is the chance that you would randomly get one with a mass of 10.81?
Zero. There are NO boron atoms with a mass of 10.81 amu. The value of 10.81 is an average of the masses of the isotopes of boron.There are two stable isotopes of boron: boron-10 and boron-11, with masses of 10.012 amu and 11.009 amu. B-10 has a relative abundance of 19.9% and B-11 has a relative abundance of 80.1%.Do the math:10.012 x 0.199 + 11.009 x 0.801 = 10.81 amu

What is is the result when you total the individual relative abundance?
the result is 1.00, because relative abundance is just the percent abundance in decimal form. The percent abundance sum is 100%, therefore the answer is 1.00 because the decimal of 100% is 1.00
Europium has a mass of 150.9196amu and a mass of m152.9209amu the average atomic mass of Eu is 151.96amu calculate the relative abundance of the two europium isotopes?
Europium 150.9196 has relative abundance of 51.99%, while Europium 152.9209 has a relative abundance of 48.04% (Assuming that these are the only 2 isotopes of Europium
What is hydrogens relative abundance in the atmosphere?
It is the most abundant element!
How do you figure out relative abundance?
Relative abundance is typically calculated by dividing the number of individuals of a particular species by the total number of individuals in a community and expressing this as a percentage. This helps to compare the presence of different species in a community. Additional methods, such as quadrat sampling or transect sampling, can be used to estimate relative abundance in ecological studies.

What is is relative abundance?
The concentration of each isotope of a natural chemical element.

The relative abundance of each isotope of an element is used to determine its atomic mass. This is the weighted average of all naturally occurring isotopes.
How does a mass spectrograph show the relative abundance of isotopes of elements?
in modern instrument,each ion strikes a detector,ionic current is amplified and is fed to the recorder. The recorder makes a graph showing the relative abundance
