Does beryllium have a positive or negative charge?

Beryllium, as an element, typically does not have a positive or negative charge on its own in its neutral state. It has an atomic number of 4, which means it has 4 protons in its nucleus and 4 electrons surrounding the nucleus in its most stable, neutral configuration.

However, beryllium can form ions in certain chemical reactions where it either loses or gains electrons. When beryllium loses electrons, it forms positively charged ions, typically Be^2+, by losing its two valence electrons. When it gains electrons, it can form negatively charged ions, although this is less common.

In its natural state, beryllium is electrically neutral, but it can form ions with positive charges under specific conditions.
