Please mention at what problems you think.
1. Radium has 88 protons. 2. Radium has not... americium !
The combination of Americium and helium does not yield any specific compound or reaction that is commonly known. Americium is a radioactive element and helium is an inert gas, so they are unlikely to react with each other under normal conditions.
The element named for a Cajun country is Americium, which is named after the United States of America.
An element with an atomic number greater than 92 is considered a transuranium element. These elements are artificially created in a laboratory and are generally unstable, undergoing radioactive decay. Examples include neptunium, plutonium, and americium.
Synthetic elements are unstable chemical elements not naturally found on the earth. They are synthesized in the laboratory. All of them are unstable and radioactive in nature, which means they emit radiations and decay into other elements.
This statement is incorrect. Synthetic elements are created in laboratories, and can have any number of protons. For example, elements like americium (95 protons) and seaborgium (106 protons) are synthetic.
Any americium in a kettle !
Americium tribromide hasn't any important use now.
So-called NON-transition metals is not a defined group of elements, other than "All other elements that are NOT transition elements".
Oxygen is an element and don'y contain any other element.
No. Kryptonite is a nobel gas, and doesn't react with any other elements.
Gold is an element
