Boron: Boron's mass number is 10.811 rounded to 11.
11 - 5 (Z or element number) = 6
The mass number of an atom, also known as the atomic mass number, is the sum of protons and neutrons in the nucleus. In this case, an atom with 6 protons and 10 neutrons would have a mass number of 16.
Basic arithmetic (5+6) suggests that the atomic mass is eleven.
The atomic mass number is calculated by adding the number of protons and neutrons in the nucleus. In this case, the isotope with atomic number 5 and 6 neutrons would have an atomic mass number of 11 (5 protons + 6 neutrons = 11 atomic mass number).
Beryllium-10 has 4 protons and 4 electrons. Since the atomic number of beryllium is 4, this is how many protons and electrons it has. Beryllium-10 is an isotope, which means it has 6 neutrons, as the total mass number of beryllium-10 is 10.
This atom has three neutrons. The atomic mass number is the sum of the protons and neutrons. All atoms of the same element have the same number of protons (lithium has three), so the neutrons have to account for the rest of the mass. 6 (the mass number)-3 (the number of protons in a lithium atom)=3. So this atom must have three neutrons.
The mass number of an atom, also known as the atomic mass number, is the sum of protons and neutrons in the nucleus. In this case, an atom with 6 protons and 10 neutrons would have a mass number of 16.
Boron: Mass is 10.811 11 - 5 (Z or element number) = 6 neutrons.
If carbon has a mass number of 12, it means it has 6 protons (since the atomic number of carbon is 6). To find the number of neutrons, you subtract the number of protons from the mass number. Therefore, carbon-12 would have 6 neutrons.
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.
Mass number is the total number of protons and neutrons.
The mass number is the sum of protons and neutrons in an atom. Boron typically has 5 protons, so if it possesses 6 neutrons, the mass number would be 11 (5 protons + 6 neutrons).
A carbon atom with a mass number of 12 has 6 protons (which is the atomic number of carbon) and 6 neutrons.
Basic arithmetic (5+6) suggests that the atomic mass is eleven.
The atomic mass number is calculated by adding the number of protons and neutrons in the nucleus. In this case, the isotope with atomic number 5 and 6 neutrons would have an atomic mass number of 11 (5 protons + 6 neutrons = 11 atomic mass number).
The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. In this case, with 5 protons and 6 neutrons, the mass number of the boron atom would be 5 + 6 = 11.
The mass number of an atom is the total number of protons and neutrons in its nucleus. Therefore, the mass number of boron with 5 protons and 6 neutrons is 11.
Carbon's atomic number is 6, therefore it has 6 protons in its atoms. Mass number is the sum of protons and neutrons in the nucleus, which is 6 + 5 = 11.
