How were Alpha decay and beta decay discovered?
Alpha, beta, and gamma radiation were first observed from a sample of Radium in a magnetic field.
Which statement describes a major drawback of the Bohr model that caused scientists to replace it?
According to the work of the Curies, which action would increase the radioactivity of polonium? Dissolve the polonium in a solvent.Heat the polonium until it becomes a gas.Expose the polonium sample to light.Increase the amount of polonium.
What did madam Marie curie discover?
Curie did not discover radiation -- Henri Becquerel did. Curie simply showed that the amount of radiation coming from uranium compounds depended only on the amount of uranium in the sample, not on the chemical make-up of the compound. This strongly suggested that the radiation was coming from the atoms of uranium themselves, a revolutionary idea for its time. The Curies later found other elements that were radioactive; radium being the most intense of those.
Are plutonic rocks intrusive and generally consist of mineral grains that are coarse enough to be readily visible in a hand sample?
Yes, They Are.
What is the purpose of incubation in DNA extraction?
This is to give a period of time for the DNA to grow by replication; this allows there to be enough of a sample of DNA to extract.
What is Marie curies scientific explorations?
She and her husband studied radioactive elements. They purified a sample a radium, the first ever done. She continued working in chemistry and physics after her husband's death until her death of cancer, probably from the radiation in her work.
How many grams of a 35 gram sample of radium will decay in 5000 years if the half-life of radium is 1602 years?
approx. 31 g.
What fraction of a radium sample will remain after 3240?
The answer depends on 3240 WHAT: seconds, days, years?
Fix the PH and Radium in your well water?
Get a sample analysed at a lab FIRST -so you know what to do .
How were Alpha decay and beta decay discovered?
Alpha, beta, and gamma radiation were first observed from a sample of Radium in a magnetic field.
Is sample a noun?
Yes, the word 'sample' is a noun (sample, samples), a verb (sample, samples, sampling, sampled), and an adjective.Examples:Would you like to try a sample of our fudge? (noun)Yes, I will sample the fudge. (verb)A sample taste is not enough. I will take a pound. (adjective)
Characteristics of a good sample?
1. the sample should be representative thus carefully selected. 2. the sample should be adequate thus significant enough.
What is a short draw in Phlebotomy?
When you do not obtain enough blood for a sample.
What are the uses of DNA cloning in Forensic Science?
To produce enough copies of a DNA sample, that identification can be made of the source of the DNA sample.
What if there is not enough water in a cylinder to cover a sample?
then you would have a problem to find out the right amount of volume of the sample that you dropped in the cylinder.
What is a sample size?
When something is a sample size, that means it is smaller than the size that is normally available for purchase. Sample size products are usually enough to let you try something before you buy it.
