americium

The crystal structure of americium changes with pressure and temperature.

Americium does not occur in nature; it is artificially created.

The longest half life of any type of americium is 7370 years.

Americium 241 has a half-life of about 450 years.

Sixteen isotopes of americium are known with mass numbers from 232 to 248.

Americium is a synthetic element that has the symbol Am and atomic number 95.

This is how elements such as neptunium, plutonium, and americium are made.

Americium is produced mostly artificially in small quantities, for research purposes.

About 19 isotopes and 8 nuclear isomers are known for americium.

Tests are already being conducted in which americium is being used as a fuel.

Americium (Am) is an artificial element, and thus a standard atomic mass cannot be given.

It is a synthetic element, made from a fusion reaction between americium and calcium.

Its toxicity is comparable to, but slightly lower than that of americium and plutonium.

His intention was to obtain Americium, a radioactive substance, from the detectors.

Americium is a relatively soft radioactive metal with silvery appearance.

Most household smoke detectors contain americium produced in nuclear reactors.

Metallic americium is obtained by reduction from its compounds.

Tetravalent americium has also been observed in the aqueous phase.

Americium is made by bombarding a plutonium target with neutrons.

A large amount of work has been done on the solvent extraction of americium.

Americium readily reacts with oxygen and dissolves well in acids.

In this sense, americium is chemically similar to most lanthanides.

Americium-241 is the most prevalent isotope of americium in nuclear waste.

Americium, a radioactive substance created by plutonium when it gives off its radiation, has already turned up in the river, she said.

Each calcium nucleus contains 20 protons and americium 95.
