An ion has atomic number 29, mass number 65 and also a fee of 2+. How plenty of protons does the ion contain? How numerous neutrons go the ion contain? How countless electrons does the ion contain? What is the chemical symbol for this element?
You are watching: Cu number of protons in ion
one ion has actually atomic number 29, fixed number 65 and a fee of two plus. How many protons walk the ion contain?
normally speaking, one ion is one atom or molecule that has lost or gained electrons. Because that instance, lithium can type a lithium ion by offering up one electron. The ion in this question has actually properties of atomic number, mass number, and charge. Atom number and mass number only use to single atoms. Therefore this ion need to be acquired from one atom.
What the inquiry is questioning is how plenty of protons there room in the cell core of this ion. To answer this question, we have the right to fall ago on the meaning of the atom number. The atom number describes the number of protons in the cell nucleus of the atom or ion it refers to. In our case, the atomic number of the ion is 29. Therefore this ion contains 29 protons.
How plenty of neutrons go the ion contain?
The mass variety of an ion or atom refers to the variety of protons to add the number of neutrons in the nucleus. This ion has actually a mass number of 65. This provides us the equation that the variety of protons to add the variety of neutrons for this ion is same to 65.
From part a) we recognize that the variety of protons is equal to the atom number, i beg your pardon is 29. So the variety of neutrons in this ion is same to 65 minus 29, i m sorry is same to 36.
How many electrons walk the ion contain?
The fee of an atom or ion is same to the number of protons minus the variety of electrons. This is because protons have a one add to charge. And also electrons have actually a one minus charge. Because we’re provided the fee of this ion, we have the right to work out how numerous electrons the contains. Because that this ion, the variety of protons minus the variety of electrons is equal to two.
together before, we understand that number of protons is same to the atomic number, which is 29. So we can rearrange the equation in regards to the variety of electrons to equal 29 minus two, which is equal to 27. We can examine that this makes sense by looking in ~ 27 minus and 29 plus, i beg your pardon will have actually an as whole charge of 2 plus. So we’ve demonstrated that this ion will contain 27 electrons.
What is the chemistry symbol because that this element?
for this reason this ion has an associated element. And also the element has an aspect symbol. Every facet is uniquely determined by its atomic number. In this case, we’re in search of the element with atomic number 29. Where must we look? ~ above our regular table. The routine table has all the known elements and contains much information around them. Each facet on the periodic table has actually its very own cell, which has at the top its atomic number and also in the center its element symbol. So we’re in search of the 29th element, the cabinet which has 29 in ~ the top. And then we’re walk to find the chemical symbol.
If girlfriend look in ~ your periodic table, you’ll watch the aspect with atom number 29 is copper, v the prize Cu. Therefore the chemical symbol because that the facet associated through this ion is Cu.

If you wanted to, you might represent all the details in this inquiry in nuclide notation favor this, wherein the chemistry symbol Cu has actually the connected atomic number, mass number, and charge.
