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!
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).
It boron element. Atomic mass of it is 10.8.
Atomic Mass Number Of Boron.The Atomic Mass Number Of Boron Is 10.81 Its Atomic number is 5. It has 5 p neutrons , 6 neutrons and 5 electrons. Its valency is 3. it has 3 valence electrons.

Boron: Mass is 10.811 11 - 5 (Z or element number) = 6 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).
It boron element. Atomic mass of it is 10.8.
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.
To calculate the number of neutrons in boron, subtract the atomic number from the atomic mass. The atomic number of boron is 5, and the atomic mass is around 10.81. Therefore, boron has approximately 6 neutrons (10.81 - 5 = 5.81).

Boron typically has 5 neutrons, as the mass number is the sum of the protons and neutrons in the nucleus. In this case, with a mass number of 10, and Boron having 5 protons (atomic number 5), the number of neutrons is 5 (10 - 5 = 5).
To find the number of neutrons in an atom, subtract the atomic number from the mass number. Therefore, for an atom with a mass number of 10 and an atomic number of 4, there would be 6 neutrons (10 - 4 = 6).
Berylium is a non metal element. Atomic mass of it is 9.
The atom with a mass number of 11 and 6 neutrons is boron. Boron has an atomic number of 5, which means it has 5 protons in its nucleus. To find the number of neutrons, subtract the atomic number from the mass number: 11 (mass number) - 5 (atomic number) = 6 neutrons.
