What is the highest temperature for germanium?

What is the highest temperature for germanium?

(iii) Greater working temperature. The structure of germanium will be destroyed at a temperature of approximately 100°C. The maximum normal working temperature of germanium is 70°C but silicon can be operated upto 150°C. Therefore, silicon devices are not easily damaged by excess heat.

What is the boiling point of germanium?

5,131°F (2,833°C)

What element has an AR value of 32?

Germanium

How do you calculate MR and AR?

You can calculate AR by dividing your total revenue (TR) by your quantity sold:

1. AR = TR/Q. Marginal Revenue vs.
2. MR = ΔTR / ΔQ. AR = TR/Q.
3. MR = ΔTR (1,045 – 1,000) / ΔQ (11 – 10) = 45.
4. MR = ΔTR (1,080 – 1,045) / ΔQ (12 – 11) = 35.
5. TR = P x Q.
6. TR (500) = P (10) x Q (50)
7. MR = ΔTR (549.45 – 500) / ΔQ (55 – 50) = 9.89.

How do you calculate the AR?

To calculate M r for a substance:

1. work out how many atoms of each element are in the chemical formula.
2. add together the A r values for all the atoms of each element.

What is the AR of an element?

The relative atomic mass of an element is the average mass of its atoms, compared to 1/12th the mass of a carbon-12 atom. The relative atomic mass, A r, of an element is calculated from: the mass numbers of its isotopes.

Is MR and AR the same in chemistry?

(6) For molecules Mr is the relative molecular mass or molecular weight; for atoms Mr is the relative atomic mass or atomic weight and the symbol Ar may be used.

What is the formula for Percent abundance?

As a percent, the equation would be: (x) + (100-x) = 100, where the 100 designates the total percent in nature. If you set the equation as a decimal, this means the abundance would be equal to 1. The equation would then become: x + (1 – x) = 1. Note that this equation is limited to two isotopes.

Is CL 35 or CL 37 more abundant?

Chlorine naturally exists as two isotopes, 17 35 Cl (chlorine-35) and 17 37 Cl (chlorine-37). The abundance of chlorine-35 is 75% and the abundance of chlorine-37 is 25%. This is because the chlorine-35 isotope is much more abundant than the chlorine-37 isotope.

How is relative abundance calculated?

It is usually measured as the number of individuals found per sample. Relative species abundance is calculated by dividing the number of species from one group by the total number of species from all groups.

What do you call the element from atomic number 57 to 71?

The elements from atomic number 57 to 71 are called Lanthanides. They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. The lanthanides are between Barium and Hafnium.

What is difference between atomic weight and atomic mass?

Atomic weight is the weighted average of the naturally occurring isotopes. So again, the mnemonic for memorizing the difference between atomic mass and atomic weight is: atomic mass is the mass of an atom, whereas atomic weight is the weighted average of the naturally occurring isotopes.

Is atomic number the same as atomic mass?

Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element’s nucleus. It is the average weight of an element. It is the total number of protons in the atom’s nucleus.

What are the first 10 elements?

What are the First 10 Elements

Name of the Element	Symbol of the Element	Atomic Number
Boron	B	5
Carbon	C	6
Nitrogen	N	7
Oxygen	O	8

How can I memorize the periodic table easily?

Memorization Strategies

1. Break down the table into sections.
2. Spread out the memorization process.
3. Learn the elements in a song.
4. Make nonsense words made from element symbols.
5. Use color to learn element groups.
6. Use a mnemonic device to help remember the order of the elements.
