An ion of copper, Cu+2, has 27 electrons and a charge of +2. The copper atom has loaned out (or had borrowed from it) in a chemical reaction, those 2 electrons. An ion is formed any time the number of electrons an atom has does not equal the number of protons in its nucleus. The 2 electrons plus 27 electrons makes 29 electrons - just the number that are present in a neutral atom of copper.
What else can I help you with?
What has 23 protons and 22 electrons?
-4. There are four more electrons than protons, and the charge of each is precisely opposite.
What is the total number of protons in an atom that has 24 electrons and 25 neutrons?
There can not be an atom with more electrons than protons, however to find the atomic mass of any atom disregard the electrons and add the number of protons and nuetrons together. The previous answer is correct in that the atomic mass is equal to the number of protons plus the number of neutrons. The atomic number is the number of protons and in a neutral atom the number of protons and electrons are equal. Atoms have can have a charge, they are then called ions. The way the become charged is either through the loss (oxidation) or gain (reduction) of electrons. Therefore it is possible to have a charged atom with more or less electrons than protons.
How many electrons are in a nickel ion that has an atomic number of 28 and a positive charge of 2 how do you know?
An atomic number of 28 implies that a neutrally charged atom would have 28 electrons. If it has a positive charge of +2 then that would imply the ion was deficient by 2 electrons - hence a total of 28-2 = 26 electrons.
How many protons and electrons does a chloride ion have?
Protons = 17, electrons = 18There are two isotopes differing in neutron number only :Cl-35 (75%) having 35-17= 18 neutronsCl-37 (25%) having 37-17= 20 neutrons

How many protons neutrons and electrons are in the element manganese?
Manganese has 25 protons, 25 electrons and 30 neutrons.
How many electrons and neutrons and protons are in manganese?
Manganese has 25 protons, 25 electrons and 30 neutrons.
What atom has 17 protons 18 electrons and 18 neutrons?
It is NOT an atom but a 1+ ion of Chlorine Cl+ (atomnumber 17, massnumber 17+18=35) isotope 35.
How many protons are in magnesium?
The atomic number of magnesium is 12. So there are 12 protons
How many electrons dose manganese have?
25 electrons.... ( as the number is 25 : being 25 protons and 25 electrons)
If an atom has 12 protons 13 neutrons and 12 electrons what is the charge of the atom?
It has no charge because the protons (positive) and the electrons (negative) number the same. The charges cancel out, which means it's a neutral atom.
What is the protons neutrons and electrons of manganese?
Manganese has 25 protons and electrons and 30 neutrons.
How many protons neutrons and electrons are in the isotope 52Mn?
The symbol Mn indicates a manganese atom, which always has 25 protons. The electroneutrality required for any atom requires the presence of 25 electrons to balance the electrical charge of the 25 protons. The mass number, 52 in this instances, is the sum of the numbers of protons and neutrons. Therefore, the number of neutrons in the isotope is 52 - 25 or 27.
