Elements in group 1 and group 2 are metals. Atoms of group 1 elements have one electron in their outer shell, and atoms of group 2 elements have two electrons in their outer shell. Elements in ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

This leaves one silicon atom with a vacant location in its outer shell, called a "hole," that readily accepts an electron. Because the charge carriers are holes, p-type silicon is said to have a ...

Nevertheless, the fact that the francium atom has the largest diameter of any element, at a huge 2.7 ångströms, and the fact that it has just one outer-shell electron, has made it the object of ...

Its name is derived from the Latin rubidus, meaning deepest red, which relates to the colour seen after excitation of the single electron in its outer shell. Rubidium is actually one of our commoner ...

In atoms with filled electron shells, these magnetic moments ... But in atoms with unpaired electrons in their outer shells, there’s nothing to cancel out the magnetic moments, which means ...

A supposedly stable belt of radiation 7000 km above the Earth’s surface may in fact be producing damaging bursts of ...

Our cells are made of atoms. Atoms are surrounded by electrons. Atoms are stable when the electrons in the outer shell are in pairs. If the atom loses an electron, that atom will be unstable. To ...

The new book Seeds: Time capsules of life by visual artist Rob Kesseler and botanist Wolfgang Stuppy explores these tiny ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as their name implies. A stable ...
