Boron Boron Boron

Boron's atomic number is 5, meaning 5 protons and 5 electrons.

Boron's Relative Atomic Mass is approximately 10.8

To find neutrons, you subtract the atomic number from the atomic mass.

10.8 - 5 = 5.8 (or 5)

Boron has 5 protons, 5 electrons and 5.8 neutrons

There is no element that has 5 protons 5 neutrons and 5 electrons.

The element is sulphur. It has 5 valence electrons and 16 neutrons.

The element with 5 fewer electrons than sodium is not a gaseous element!

Beryllium-9: 4 protons and electrons, 5 neutrons

Boron has 5 protons and electrons. Boron-11 would be the isotope that has 6 neutrons.

The isotope boron-11 has 5 protons and 6 neutrons, but also 5 electrons not 8.

It should be Boron, but the neutrons in it can vary. However, the electrons and protons in an element are always constant.

The element in Period 5 with 51 neutrons and 40 electrons is Zirconium (Zr).

Since Boron's atomic number is 5, it has 5 protons and 5 electrons. The standard boron atom has 6 neutrons in it.

boron10 would be the isotope that matches these descriptions

It is the boron element. It contains similar numbers of electrons and protons.

Boron has 5 protons and electrons and 6 neutrons. The symbol for Boron is B and its atomic number is 5.

I think that's B, the symbol for the element boron. Boron has 5 protons and 5 electrons. The most common isotope has 6 neutrons. The other main isotope has only 5 neutrons.

no element, Be (Berylium) has 4 electrons and 4 protons, but 9 neutrons when you take 4 away for the 9 you get 5. so there isn't an element that has all 4's

Boron 10: 5 protons, 5 neutrons, 5 electrons Boron 11: 5 protons, 6 neutrons, 5 electrons

Any atom with 4 protons is an atom of beryllium. If the atom is neutral, it must also have 4 electrons. However, 5 neutrons specifies an isotope, specifically Be-9, rather than an element as such.

That seems to be an invalid notation. The subscript refers to the number of protons (5=Boron), but 'C' refers to the element (Carbon). Ignoring the 'C', Protons: 5 (Boron) Neutrons: 13-5= 8 Neutrons Electrons: 4+5= 9 Electrons

Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.

Any atom with 5 protons is Boron, and a neutral (no net electrical charge) boron atom will also have 5 electrons. A Boron atom with 4 neutrons is Boron-9, a highly unstable isotope.

In identifying an element the only thing that matters is the number of protons. Since there are 7 protons the element is nitrogen.
