What is atomic mass number?

The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. The mass number is different for each different isotope of a chemical element.

Is the mass number A whole number?

The symbol is read "uranium-238." The mass number is always a whole number; it is a count of the particles. It differs from the exact mass of the atom in atomic mass units, amu, which is often known and expressed to six decimal places.

What is the last element in Period 4?

Krypton

How many protons and electrons does gold have?

It is classified as a transition metal. Gold atoms have 79 electrons and 79 protons with 118 neutrons in the most abundant isotope.

Is gold on the periodic table?

Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.

Who discovered the element gold?

Gold is element 79 and its symbol is Au. Though the name is Anglo Saxon, gold originated from the Latin Aurum, or shining dawn, and previously from the Greek. It's abundance in the earth's crust is 0.004 ppm.

Why is Iridium expensive?

Iridium: $53 per gram Iridium is the most corrosion-resistant metal on the planet and is routinely used as a hardening agent for platinum alloys. The reason it's so expensive at $53 per gram is that it's one of the rarest elements found in the Earth's crust.

What type of element is oxygen?

Oxygen is the eighth element of the periodic table and can be found in the second row (period). Alone, oxygen is a colorless and odorless molecule that is a gas at room temperature. Oxygen molecules are not the only form of oxygen in the atmosphere; you will also find oxygen as ozone (O3) and carbon dioxide (CO2).

Where is iridium found?

Iridium generally is produced commercially along with the other platinum metals as a by-product of nickel or copper production. Iridium-containing ores are found in South Africa and Alaska, U.S., as well as in Myanmar (Burma), Brazil, Russia, and Australia.

Who discovered the element iridium?

Smithson Tennant

What is Iridium worth?
