its 6
The atomic/proton no. of beryllium is 3. Thus the number of protons is 3.
AnswerProtons = 4Neutrons = 5There are four protons, four electrons, and five neutrons.You can find the number of protons by looking and the atomic number, and because this atom is not an ion (a charged atom), the number of protons and electrons are equal.You can find the number of neutrons by subtracting the number of the protons from the atomic mass. In this case, 9 minus 4 equals 5 for the number of neutrons. Your atom is the element beryllium, and is specifically the one stable isotope of that element, 9Be.
The number of neutrons in an atom can affect the atomic mass of an atom.
The neutron was discovered by James Chadwick in 1932 through his experiments involving the bombardment of beryllium with alpha particles. Chadwick's discovery confirmed the existence of the neutron as a neutral subatomic particle with a mass similar to that of the proton.
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
Beryllium typically has 4 neutrons in its nucleus, so an isotope with 5 neutrons would have a mass number of 9. Therefore, the atomic mass of beryllium with 5 neutrons would be approximately 9 atomic mass units (amu).
Since the mass number is protons plus neutrons, it would have 5 neutrons.
Beryllium has an atomic number of 4, which indicates the number of protons in its nucleus. Its atomic mass of 9 includes the total number of protons and neutrons in its nucleus. This means that beryllium has 4 protons and usually 5 neutrons.
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).
The most common isotope of Beryllium is Beryllium 9, which has 5 neutrons.
Berylium is a non metal element. Atomic mass of it is 9.
Beryllium 9 has 5 electrons.
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.
The atomic mass of an element is determined by the sum of the protons and neutrons in its nucleus. Beryllium has 4 protons and typically 5 neutrons, resulting in a total of 9 nucleons (protons + neutrons). This is why its atomic mass is 9 instead of 8.
A neutral beryllium atom has four neutrons. This is because beryllium's atomic number is 4, which means it has 4 protons in its nucleus, and since it is neutral it also has 4 electrons to balance the charge.
Beryllium has 5 neutrons.
neutrons in berylium are 5 because Atomic mass - 9 Atomic number - 4 number of neutrons = Atomic mass - Atomic number = 9 - 4 = 5 neutrons = = berylium is metal = no berylium is not a true metal most of its properties are similar to the non metals.....
