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 more valence electrons than oxygenfewer valence electrons than neon more protons than sodium but fewer protons than argon?

Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.

What element has more valence electrons than oxygenfewer valence electorns than neon more protons than sodium but fewer protons than argon?

Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.


Does the valence electrons equal the number of protons?

No, the number of valence electrons does not necessarily equal the number of protons in an atom. The number of valence electrons is determined by the group number of the element in the periodic table, while the number of protons is the atomic number of the element.


What this element has five valence electrons shows properties of metals and non metals and has 33 protons in the nucleus of each atom?

Arsenic


Is the number of valence electrons equal to the number of protons?

No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.


What is the number of protons in the nucleus or the number the electrons in the energy levels called?

The number of protons in the nucleus is called the atomic number and is equal to the number of electrons in a neutral atom.


The name of the element that has 2 valence electrons and 12 protons?

Magnesium


What element has more valence electron that oxygen few valence electrons than neon more protons than sodium but fewer protons than argon?

The element described has more valence electrons than oxygen but fewer than neon, more protons than sodium but fewer than argon. This element is magnesium, which has 12 protons, 12 valence electrons (2 more than oxygen but 2 less than neon), and is situated between sodium and argon on the periodic table.
