How many neutrons are in a neutral beryllium atom?
An element is defined as atoms with the same number of protons (and thus electrons). Beryllium has 4 protons and 4 electrons. The number of neutrons is determined by subtracting the atomic number from the atomic mass. At least three isotopes of Beryllium have been identified but there is only one stable naturally occurring isotope - Beryllium 9. If there are 4 protons, there must be 9 - 4 = 5 netrons in this isotope. The other stable isotope is beryllium 10 with a half life of 2,700,000 years and this must have 6 neutrons. This does not occur naturally but is made in atomic reactors. The other identified isotope is Beryllium - 8 which is made in the same way but immediately splits into two helium nuclei. So for most naturally occurring Beryllium, there are 5 Neutrons.
How many protons for ion Be2 plus?
The atomic number of beryllium (Be) is 4 and the atomic mass is 9 for the most stable isotope. Be-9 isotope has 5 neutrons (9 - 4 = 5).Beryllium's stable isotope (Be-9) has 5 neutrons. There are about 11 other isotopes known, Be-7 and -10 the next most common and have 3 and 6 neutrons respectively but only exist in nature in trace amounts.
What is the atomic number of an atom with mass number 9 and 5 electrons?
The atomic number is the number of Protons The mass number is the number of Protons and Neutrons The number of Electrons always equals the number of Protons Therefore according to the above information the atomic number of the atom is 5 HOWEVER there is NO element with a mass number (atomic mass) of 9 with an atomic number of 5. You question is impossible to answer. Beryllium has an Atomic mass of 9.0122 and an Atomic number of 4 Boron has an Atomic mass of 10.811 and an Atomic number of 5
What is the atomic mass number of an isotope that has an atomic number 5 and includes 6 neutrons?
The atomic mass is, basically, the sum of the protons (the "atomic number"), and the number of neutrons.
How many protons neutrons electrons are found in the beryllium atom?
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.
If beryllium has an atomic number of 4 and an atomic mass of approximately how many neutrons does beryllium atom have?
Since the mass number is protons plus neutrons, it would have 5 neutrons.
What is the atomic mass of an element with 4 protons 5 neutrons and 4 electrons?
4 protons 4 electrons 5 neutrons subtract the number of of protons from the atomic weight
Beryllium has a atomic number of four and a atomic mass of 9 beryllium has?
Therefore beryllium has 4 protons, 4 electrons and 5 neutrons.
What is the Mass number in beryllium?
The atomic mass is the same as the atomic weight therefore it is 9.01218. Beryllium is a non metal element. Atomic mass of it is 9.01. The atomic mass number, which is distinct from the atomic mass and the atomic weight, is 9.
How many neutrons and electrons does berylluim?
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.....
What is the atomic number of an atom that has a mass of 9 and 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).

What is the mass of beryllium with 5 neutrons?
its 6
An element has 4 protons 5 neutrons and 4 electrons What is the atomic mass of the element?
That would Beryllium, with an atomic number of 4 and mass number of 9Hope this helped!
How many protons for ion Be2 plus?
The atomic number of beryllium (Be) is 4 and the atomic mass is 9 for the most stable isotope. Be-9 isotope has 5 neutrons (9 - 4 = 5).Beryllium's stable isotope (Be-9) has 5 neutrons. There are about 11 other isotopes known, Be-7 and -10 the next most common and have 3 and 6 neutrons respectively but only exist in nature in trace amounts.
Why does beryllium have an atomic mass of 9 instead of 8?
This is because one stable isotope has 5 neutrons in addition to 4 protons making the mass 9 not 8.
What types of particles are found in the nucleus of a beryllium?
The atomic nucleus of beryllium contain 4 protons and 5 neutrons.
