Cu2 plus has how many protrons and electrons?
Cu2+ has 29 electrons (since copper has 29 protons) and 27 protons, after losing 2 electrons to become a positively charged ion.
What is the chemical symbol for an ion with 29 protons and 27 electrons?
The chemical symbol is Cu2+.
How many protons are in a copper ion with a positive 2 charge?
The atomic number of copper is 29. Thus, neutral copper would have 29 protons and 29 electrons. However, since we're dealing with Cu2+, we need to subtract 2 electrons from that number, leaving us with 27.
What is the charge on an atom of copper that has lost two electrons and how is this ion represented?
+2 is the charge represented Cu2+
Why copper has 2 plus oxidation state?
Copper can have a +2 oxidation state because it can lose two electrons from its outermost shell to achieve a stable electron configuration. This results in the formation of Cu2+ ions with a charge of +2.
Cu2 plus has how many protrons and electrons?
Cu2+ has 29 electrons (since copper has 29 protons) and 27 protons, after losing 2 electrons to become a positively charged ion.
What is the chemical symbol for an ion with 29 protons and 27 electrons?
The chemical symbol is Cu2+.
What species has the greatest number of electrons I- or Cu2 plus or Fe3 plus or Au or Hg?
Au (gold) has a total of 79 electrons, making it the species with the greatest number of electrons among the options provided.
Is Cu plus 2 a cation or anion?
Cu2+ is a cation as are all positive ions. One way to remember is to think of the "t" in cation as a plus sign.
What element has 29 protons and 35 neutrons and 27 electrons?
Copper has an atomic number of 29 - so it has 29 protons-- when it has only 27 electrons so it is Cu2+ . The isotope is copper-64
How many protons are in a copper ion with a positive 2 charge?
The atomic number of copper is 29. Thus, neutral copper would have 29 protons and 29 electrons. However, since we're dealing with Cu2+, we need to subtract 2 electrons from that number, leaving us with 27.
What is the chemical for the ion with 29 protons and 27 electrons?
It would end up answering with Cobalt = Co. Because the protons stay the same and add the protons and electrons together equaling 59. So (Co+2) would be the final answer.
What is the stock name for Cu2 plus?
The stock name for Cu2+ is copper(II).
What if the formula for Cu2 plus and Iodine minus?
Cu2+ + I- --> Cu2I The compound created is Copper(I) Iodide
What is the correct cell notation for the reaction 2Au plus aq plus Cus 2Ausplus Cu2 plus aq?
Cu(s) | Cu2+(aq) Au+(aq) | Au(s)
Do Cu plus and Cu2 plus plus violate the octet rule?
Yes, both Cu+ and Cu2+ violate the octet rule. Copper (Cu) is an exception to the octet rule due to its electron configuration, which allows it to have a partially filled d orbital. This leads to Cu forming compounds where it does not achieve a full octet of electrons.
What is the charge of the ion with 27 protons and 25 electrons?
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.
