How many years would it take half of the rubidium atoms in a piece of a rock to change into strontium?
The time it takes for half of the rubidium atoms in a sample to change into strontium is determined by the half-life of rubidium-87, which is approximately 48.8 billion years. This means that it would take about 48.8 billion years for half of the rubidium-87 atoms to decay into strontium-87.
How many years would it take half of the rubidium-87 atoms in piece of rock to change into strontium-87?
The half-life of rubidium-87 is approximately 48.8 billion years. This means it would take about 48.8 billion years for half of the rubidium-87 atoms in a rock sample to decay into strontium-87. Therefore, to see half of the rubidium-87 atoms change into strontium-87, you would need to wait this extensive period.
What metal ion would you predict to be contained in sample of unknown 1?
Strontium and copper nitrate
What is the symbol for an ion having 35 protons and 36 electrons and 45 neutrons?
This is the anion of the isotope arsenic-73: 73As3-; it is impossible to write correct in WikiAnswers.
Is strontium chemically similar with calcium or rubidium?
Cesium. For non-transition elements such as rubidium, cesium, and strontium, the most chemically similar element to any other element is always one in the same column of the Periodic Table but in an adjacent row. Since strontium is not in the same column as rubidium but cesium is in the same column and an adjacent row, the answer follows. (This rule is sometimes true also for transition elements, but not always: For example, for elements in columns 8, 9, and 10, the most nearly chemically similar element is one in the same row and an adjacent column within this group, rather than one in the same column but an adjacent row.)
What is the formula and name for Rb O?
Rb is rubidium, O is oxygen. They will combine to form Rb2O which is called rubidium oxide.
What is the mass percentage of strontium in strontium sulfide?
To calculate the mass percentage of strontium in strontium sulfide, you need to know the molar mass of strontium sulfide (SrS), which is 119.63 g/mol. The molar mass of strontium (Sr) is 87.62 g/mol. To find the mass percentage, you would divide the molar mass of strontium by the molar mass of strontium sulfide, and then multiply by 100. This would give you the mass percentage of strontium in strontium sulfide, which is approximately 73.2%.
When rubidium react with iodine which compound will make?
Rubidium metal would react with iodine to make rubidium iodide , according to the equation: 2 Ru + I2 -> 2 RuI
What is the anion formula for strontium?
Strontium is Sr and its CATION would be Sr2+ - it does not form anions.
Would strontium and Fluorine covalently bond?
no ionic strontium is a metal and flourine is a nonmetal
What is the IUPAC name for SrBr2?
Strontium Bromide Strontium Bromide
If 3.0 grams of strontium-90 in a rock sample remained in 1989 approximately how many grams of strontium-90 were present in the original rock example in 1933?
If the half-life of strontium-90 is around 29 years, then if 3.0 grams remained in 1989, there would have been approximately 6 grams in 1933. This is because each half-life represents a halving of the original amount.
