How many protons and nuetrons are in helium?
The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".
What element has 2 valence electrons and 4 protons?
The element with 2 valence electrons and 4 protons is beryllium. Beryllium has an atomic number of 4, indicating it has 4 protons in its nucleus. The valence electrons are the outermost electrons in an atom, and beryllium has 2 valence electrons in its outer energy level.
How many protons and electrons in Be2 plus ION?
Beryllium (Be) has 4 protons and 4 electrons in its neutral state. When it forms the Be2+ ion, it loses two electrons, leaving it with 4 protons and 2 electrons. The Be2+ ion has a 2+ charge because it has lost two negatively charged electrons.

What ionic symbol has 4 protons and 2 electrons?
The ionic symbol with 4 protons and 2 electrons is Be2+, which represents the beryllium ion. Beryllium normally has 4 protons and 4 electrons, but when it loses 2 electrons to become stable, it forms the Be2+ ion.
