What is the atomic number of einsteinium?

The atomic number of an element is the total number of protons, neutrons and electrons in that element. The atomic number is also known as the atomic mass and is equal to the sum of the protons plus the sum of the electrons.

What are the properties of the atomic number and the atomic mass?

Atoms are the smallest particles that have no independent existence, but that are directly involved in chemical reactions. They are so small that they cannot be seen even with the best microscope.

What is the oxidation number?

Oxidation numbers refer to the number of electrons that an element has in its orbit. They are negative if an element has no electrons and positive if it does.

What is the electron affinity?

The electron affinity is the ability of an atom to hold and release electrons. The higher the electron affinity, the more stable the atom is.

What is the electronegativity?

Electronegativity is the ability of an atom to hold an electron. It is the ratio of the number of electrons an atom can hold to its weight.

What is the oxidation state?

An atom of an element will have a positive oxidation state if it has no electrons and a negative oxidation state if it does. The oxidation states of elements are shown on the Periodic Table.

How was einsteinium discovered?

Einsteinium was discovered in 1952 during the examination of debris from the first hydrogen bomb test. A team of scientists from the Lawrence Berkeley National Laboratory, Argonne National Laboratory and Los Alamos Scientific Laboratory, led by Albert Ghiorso, isolated minuscule amounts of the element from radioactive material in the debris.
