electrons have negligible mass. the mass of the ion depends on how many protons and neutrons are present.

What is the identity of an ion with an atomic number is 16 and mass 33 and 18 electrons?
The ion with an atomic number of 16, mass 33 and 18 electrons is the sulfide ion S2-
When it loses two electrons to become a calcium ion what is it's new mass?
38 amu EDIT: This answer is INCORRECT. Electrons do not have significant mass.
What is the mass number of an ion with 107 electrons and a 1 charge?
Mass number is the sum of the number of protons (atomic number) and neutrons in the nuclei of the atoms of an isotope of a particular element. The information given can be used to find the number of protons, which is 106. You can know this because in a neutral atom, the numbers of protons and electrons are the same. So you take away the single extra electron in the ion, and you get 106 electrons in the now neutral atom. So if there are 106 electrons, there are also 106 protons. However, you still cannot determine the mass number because the number of neutrons has not been given.
Why do you calculate the number of electrons by the atomic mass and number?
because an atomic number is the same as the number of electrons in an atom (not ion)
Why is the mass number of the ion the same as the number of isotope?
Because electrons, which are gained or lost to form ions from atoms, have so little mass compared with protons or neutrons that the electrons are ignored in the mass number.
What is the mass number of an ion with 107 electrons 159 neutrons and a 1 charge?
266
What is the mass number of an ion with 107 electrons 159 neutrons and a plus 1 charge in integer form?
If the ion has a +1 charge and has 107 electrons, that means that it originally had 108 electrons, and therefore has 108 protons. The mass number is the sum of the protons and neutrons, 108 + 159, and therefore is equal to 267.
What is the mass number of the ion?
The mass number of an ion remains the same as the element. This is because an ion gains or loses electrons which have minimal mass.
What is the identity of an ion with an atomic number is 16 and mass 33 and 18 electrons?
The ion with an atomic number of 16, mass 33 and 18 electrons is the sulfide ion S2-
When it loses two electrons to become a calcium ion what is it's new mass?
38 amu EDIT: This answer is INCORRECT. Electrons do not have significant mass.
What ion has 18 electrons and a mass number of 33 and atomic number of 16?
The sulfide ion, S2-.
Is the mass of an ion different from the mass of the atom it came from?
A small difference of mass exist because the gain or loss of electrons.

What is the mass of a calcium ion when it loses 2 electrons?
Imperceptably less than one with its full compliment. Electrons are very important particles, but they have almost no mass of their own.
Why is the mass number of the ion the same as the number of isotope?
Because electrons, which are gained or lost to form ions from atoms, have so little mass compared with protons or neutrons that the electrons are ignored in the mass number.
What is the atomic mass of an ion that contains 87 protons 136 neutrons and 86 electrons?
This is the ion of the isotope Pb-208 (Pb2+).
