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.
What element has 2 electrons 3 protons and 4 neutrons?
There is no such element: an element is neutral, so it has equal numbers of protons and electrons.Impossible:2 protons 4 neutrons and 3 electrons is the IMpossible He-1 isotope with mass number 6 (=2p+4n). Helium does not accept electrons because it is noble.Possible:2 protons 4 neutrons and 2 electrons is (elemental) Helium, isotope with mass number 6 (=2p+4n)3 protons 4 neutrons and 3 electrons is (elemental) Lithium
What element has four protons four electrons and five neutrons?
The element with four protons (atomic number) is beryllium (Be). Beryllium typically has four electrons to balance the positive charge from the protons, and the presence of five neutrons would make it an isotope of beryllium known as beryllium-9.
What element that is a metal has 28 electrons?
The element with atomic number 28 is Nickel (Ni). It is a transition metal in period 4 of the Periodic Table. It is the first element in the Nickel family. It has 28 electrons in 4 shells with 2 electrons in the outer shell.
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.
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 electrons does beryllium have in all?
Beryllium typically has 4 electrons in total. It has 2 electrons in its inner shell and 2 electrons in its outer shell.
What element has as many electrons as it has neutrons?
Helium-4 is an element that has as many electrons as it has neutrons. Helium-4 has 2 protons, 2 neutrons, and 2 electrons.
How many protons and electrons does the element Helium have?
One atom of helium contains 2 protons and 2 electrons. The most abundant isotope of helium, helium-4, has 2 neutrons. The other, rare isotope of helium, helium-3, has 1 neutron. (Source: Wikipedia)
If the atomic number of an element is five how many protons does the element have?
If the atomic number of an element is 5, the element has 5 protons. The atomic number represents the number of protons in an atom.
