Beryllium
Boron is an atom or element, and it contains protons, electrons, and neutrons.
All beryllium atoms have 4 protons and 4 electrons. The number of neutrons is characteristic of a particular isotope, not of beryllium as a whole, and may be determined by subtracting 4, the number of protons, from the mass number of the isotope.
The gaseous element with 5 valence electrons and fewer neutrons than sodium is Boron. Boron has 5 protons and 5 neutrons, while sodium has 11 protons and about 12 neutrons.
The number of protons in an element is its atomic number. Boron's atomic number is 5 - ergo, there are 5 protons. The number of neutrons in an element is the difference between the atomic mass and the atomic number of an element. boron's atomic mass is 11. Therefore, 11 - 5 = 6. There are 6 neutrons in boron. In conclusion, there are 6 neutrons and 5 protons in boron.
Oh, dude, that's an isotope of boron, specifically Boron-9. So, it's like Boron, but with a little extra somethin' somethin'. And, you know, it's got that whole 5 protons, 4 neutrons, and 5 electrons vibe going on.
Be- Beryllium
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. In this case, the element has 4 protons and 5 neutrons, so its atomic mass is 4 + 5 = 9 atomic mass units (amu). The number of electrons does not affect the atomic mass.
That would Beryllium, with an atomic number of 4 and mass number of 9Hope this helped!
Neutrons do not affect the neutrality (or charge) of an atom; protons and electrons do. In order to be neutral, the number of protons must be the same as the number of electrons.
The mass is protons + neutrons. So, if the mass is 9 and it has 5 neutrons, then there must be FOUR (4) protons. This would be the element beryllium (Be).
Boron is an atom or element, and it contains protons, electrons, and neutrons.
Boron has 5 neutrons and 5 protons for its most common isotope
All beryllium atoms have 4 protons and 4 electrons. The number of neutrons is characteristic of a particular isotope, not of beryllium as a whole, and may be determined by subtracting 4, the number of protons, from the mass number of the isotope.
4 - protons (so it is beryllium) 5 - neutrons, therefore, it is beryllium-9 (4+5 is nine)
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.
Beryllium has 4 protons, 5 neutrons and 4 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.
