What is the density of germanium?

What is the density of germanium?

around 5.5 g/cm3

How do you find the density of an element on the periodic table?

Density of an element = ( atomic mass of the element in grams )/ ( 22.4L at STP ). First the density is the mass per unit volume….

1. Take a known volume of the element.
2. Weigh it and divide the weight by g=9.81 m/s to get the mass .
3. The density is .

What is the density of germanium g mL?

5.3 g/mL

What is the chemical symbol for germanium?

Ge

What are the properties of germanium?

Pure germanium is a hard, lustrous, gray-white, brittle metalloid. It has a diamondlike crystalline structure and it is similar in chemical and physical properties to silicon. Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid.

What are three chemical properties of germanium?

Germanium (Ge), has an atomic number of 32. It is grayish-white, lustrous, hard and has similar chemical properties to tin and silicon. Germanium is brittle and silvery-white under standard conditions. Germanium under this condition is known as α-germanium, which has a diamond cubic crystal structure.

Why Germanium is called a metalloid?

1. Germanium is shiny like metals but brittle like non-metal. It shows some of the properties like metal and some like non-metals. Most important it behaves as semi-conductor like Silicon hence like silicon it is considered as metalloid.

Is germanium a good conductor of electricity?

Pure silicon and germanium are poor conductors of electricity because their outer electrons are tied up in the covalent bonds of the diamondlike framework. They are not conductors in the metallic sense of the word, but are semiconductors.

Is Phosphorus a good conductor of electricity?

It is a good conductor of electricity and is black in color. Red phosphorus is formed when white phosphorus is exposed to light or when heated, making it amorphous. Phosphorus was discovered in 1669 by Hennig Brand, an alchemist and physician of German origin.

Is oil a conductor of electricity?

Oil is an insulator and is a bad conductor of electricity.

Is gold a good conductor of electricity?

Gold is used as a contact metal in the electronics industry as it is a good conductor of both electricity and heat.

What are 5 good conductors?

The most effective electrical conductors are:

• Silver.
• Gold.
• Copper.
• Aluminum.
• Mercury.
• Steel.
• Iron.
• Seawater.

Which metal is best conductor of electricity?

What Metal is the Best Conductor of Electricity?

• Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity.
• Copper. One of the most commonly used metals to conduct electricity is copper.
• Aluminum.

What are the top 5 electrical conductors?

Copper, silver, aluminum, gold, steel, and brass are common conductors of electricity. The most highly conductive metals are silver, copper, and gold.

Which is the best insulator?

The best insulator in the world right now is most probably aerogel, with silica aerogels having thermal conductivities of less than 0.03 W/m*K in atmosphere. of aerogel preventing ice from melting on a hot plate at 80 degrees Celsius! Aerogel has its amazing properties because it’s mostly made out of air.

Which metal is poorest conductor of electricity?

Bismuth and tungsten are two metals which are poor conductors of electricity.
