How many neutrons are in a calcium ion?
it depends on the isotopes of calcium e.g. Calcium-40 has 20 electrons and 20 neutrons Calcium-44 has 20 electrons and 24 neutrons To find out the number of neutrons for Calcium you take the Isotope number (x) minus away the number of electrons (20) e.g. Calcium-x Calcium-x has 20 electrons and (x-20) neutrons.. OR you take the relative atomic mass (x) and subtract it with the number of electrons (20) (x-20) = neutrons
A positive two ion of calcium ca plus 2 would have how many protons electrons and neutrons?
A calcium ion with a charge of +2 has lost 2 electrons, resulting in an electron count of 18. Since calcium has an atomic number of 20, the number of protons remains at 20. To find the number of neutrons, subtract the number of protons (20) from the mass number (which can be found on the periodic table), which for calcium is 40, to get 20 neutrons.
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.
How is are the configurations of calcium and a calcium ion similar?
They are the same in that they have the same number of protons and neutrons. However, the number of electrons is different. The calcium 2+ ion has two less electrons than the normal calcium atom.
How many protons neutrons and electrons will positive two ion of calcium have?
A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.
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.
How many subatomic particles does an ion of calcium with an atomic number of 20 and an atomic mass of 40 hve?
atom have: 20 protons,20 electrons and20 neutrons ion have: 20 protons 18 electrons( metals lose electrons) and20 neutrons
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.
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.
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.
How many protons does an atom of Calcium have in its nucleus?
A calcium ion has 20 protons, the same as its atomic number. The number of electrons depends on the charge on the ion. For the most common calcium ion with a charge of +2, the number of electrons is 18; 20 - 18 = +2. The number of neutrons depends on the isotope that is ionized and is equal to the mass number of the isotope minus the atomic number of 20.
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.
