The "mass defect" -- the fact that the mass of an isotope is less that the sum of its nucleons is due to the fact that when nucleons combine (either by fusion, for elements with atomic number less than iron[A=26]; or fission for elements with atomic number greater than iron) there is a release of energy due to the nuclear binding force, which source of the "mass defect" you correctly identified. The energy released as a result of the binding of the nucleons is equivalent to a small amount of mass of the matter -- Einstein's famous equation: E=mc^2, so the energy release E

What is Atomic mass units of an atom that contains 8 protons 9 neutrons 8 electrons?
The atomic mass unit of an atom is the sum of the protons and neutrons in its nucleus. In this case, with 8 protons and 9 neutrons, the total atomic mass unit of the atom would be 17. The number of electrons does not significantly affect the atomic mass unit of an atom.
How many electrons are present in bromine atom with mass number of 87?
A bromine atom, regardless of its mass number, has an atomic number of 35, which means it has 35 protons and, in a neutral state, also 35 electrons. Therefore, a bromine atom with a mass number of 87 will have 35 electrons. The mass number indicates the total number of protons and neutrons, but it does not affect the number of electrons in a neutral atom.
What represents most of an atom's mass?
The nucleus of an atom represents most of an atom's mass.
The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
What adds mass to an atom but does not affect its charge?
a neutron
Does the proton affect the mass of an atom?
Yes, significantly so. One proton is approximately one atomic mass unit.
What is Atomic mass units of an atom that contains 8 protons 9 neutrons 8 electrons?
The atomic mass unit of an atom is the sum of the protons and neutrons in its nucleus. In this case, with 8 protons and 9 neutrons, the total atomic mass unit of the atom would be 17. The number of electrons does not significantly affect the atomic mass unit of an atom.
Is an oxygen atom have twice the mass of a sulphur atom?
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
What prolonged deficiency would affect thyroid?
A deficiency in the element Iodine in the diet.
How many electrons are present in bromine atom with mass number of 87?
A bromine atom, regardless of its mass number, has an atomic number of 35, which means it has 35 protons and, in a neutral state, also 35 electrons. Therefore, a bromine atom with a mass number of 87 will have 35 electrons. The mass number indicates the total number of protons and neutrons, but it does not affect the number of electrons in a neutral atom.

The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
Why do you say electrons most affect an atom's size while protons and neutrons most affect an atom's mass?
because the electron are on the out side and orbit around the nucleus (aka protons and neutrons) and take up the space
What does adding A neutron to an atom's do to the atom's mass?
Adding a neutron increases the atom's mass by about 1 AMU assuming it remains stable.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
