What is the rule for determining the mass number of an atom or ion?
The mass number of an atom or ion is determined by adding together the number of protons and neutrons in the nucleus. Protons and neutrons contribute roughly the same amount of mass to an atom, so the mass number gives a good approximation of the atomic mass.
What is the mass number of an ion with 105 electrons and 157 neutrons and a plus 1 charge?
The problem statement that the ion has a plus 1 charge means that there is one more proton than electron in the ion. Therefore, the ion contains 106 protons and 157 neutrons and thus has a mass number of 106 + 157 or 263 amu.
Does the atomic number changes when an ion is formed?
No, the atomic number remains the same when an ion is formed. The atomic number is determined by the number of protons in an atom, which does not change when an atom becomes an ion by gaining or losing electrons.
Write the symbol of the ion with a 1 plus charge atomic number 55 and mass number 133?
The element is cesium (Cs) and the cation is Cs^1+
How many neutron are there in the ion 18O2?
There are 10 neutrons in the ion 18O2. This is calculated by subtracting the atomic number of the oxygen ion (8) from its mass number (18), as neutrons are equal to the difference between these two values.
An Ion with a mass of 209 and atomic number of 84 and net charge of 4 plus?
The ion is a lead ion with a 4+ charge. Its atomic number is 84, and its mass number is 208 (since the mass number is one less than the atomic mass for this particular ion).
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-
What is the mass number of an ion with 107 electrons 158 neutrons and a 1 charge?
The mass number of an ion is calculated by adding the number of protons and neutrons. Since the ion has 107 electrons and a charge of +1, it must have 108 protons (107 electrons + 1). Therefore, the mass number is 108 protons + 158 neutrons, which equals 266. Thus, the mass number of the ion is 266.
Why is the mass number of the ion the same as the number of isotope?
The mass number of an ion is equal to the sum of the number of protons and neutrons in its nucleus. Isotopes of an element have the same number of protons but differ in the number of neutrons. Therefore, the mass number of an ion can be the same as the number of isotopes because isotopes contribute to varying mass numbers in the element.
What ion has 18 electrons and a mass number of 33 and atomic number of 16?
The sulfide ion, S2-.
What is the rule for determining the mass number of an atom or ion?
The mass number of an atom or ion is determined by adding together the number of protons and neutrons in the nucleus. Protons and neutrons contribute roughly the same amount of mass to an atom, so the mass number gives a good approximation of the atomic mass.
What is the mass of an ion with 107 electrons?
The mass of an ion with 107 electrons would depend on the specific element of the ion. You would need to know the atomic number of the element to calculate the mass accurately using the atomic mass of the element.
What is the difference in mass of Na ion and Na atom?
The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.
What is mass number of calcium ion with 18 neutrons?
48
What is the symbol for chlorine ion?
37, as the isotope is identified by its mass number.
How do you calculate the ion mass?
To calculate the ion mass, you would sum the mass of its protons and neutrons. The mass of a proton is approximately 1.0073 atomic mass units (u), and the mass of a neutron is approximately 1.0087 u. Add up the number of protons and neutrons in the ion to get the total mass.
What is the mass the calcium ion?
Iron is a meta element. Atomic Mass of it is 54. Atomic number of it is 26.
