Cu(2-) does not exist, because Cu does not gain electrons at all being a metal. When it gives off two electrons Cu(2+) ions are formed.

∙ 8y agoThe copper atom loss electrons and become Cu+ or Cu2+.

∙ 7y agoIf you start with ANY neutral atom - it need not be copper - and add two electrons, you will get a net charge of -2, since each electron has a charge of -1.

∙ 7y agoIt is -2.

Does strontium have the tendency to lose or gain electrons in a chemical reaction?
You wouldn't expect strontium to gain electrons in a chemical change.
Does figurative language includes the writers personal life?
Figurative language is a way of expressing something in a way that should not be taken literally. For example, you might say that an oxygen atom wants to gain two electrons. Oxygen atoms dotend to gain two electrons when the undergo chemical reactions, but they do not have actual desires or minds. Still, it is quite understandable if you say they want to gain two electrons. That is a figurative statement. It doesn't really have anything to do with the writer's personal life, although nothing prevents a writer from discussing his or her life in figurative terms if he or she so desires.
What is the difference between finite open loop gain and closed loop gain?
In a closed loop system the gain without the feed back loop being closed is called open loop gain!!! e.g if forward gain is "A" and feed back factor is "B" then open loop gain is "AB" and closed loop gain will be [A/(A+B)]
How do you calculate the current gain of a transistor JFET?
FETs don't have current gain as no current flows through the gate. The gain of a FET is a voltage gain and is called mu.
What is a Decibel power gain?
Generally power is expressed in watts. The gain is the ratio of the output power to the input power. Gain = (output power)/(input power) if the gain is expressed in terms of log(base10) it is known as Decibel power gain Decibel power gain = Log10(Gain)dB if 1milliwatt power is taken as reference then Decibel power gain = Log10(Output power/1 milliwatt)dBm
How the charge of an atom changes?
The gain and/or lose of electrons.
How do atoms gain a charge?
An atom willreceive a charge when it becomes ionized. If the atom looses one of its electrons (-), then there are more protons (+) and it becomes a+1 charge (positive). If the atom gains an electron, then there are more electrons and it becomes a -1 (negative) charge. It depends on the electrons in the valence level (outer level) to decide if it will gain or lose electrons.
What is the name of the bond that takes place when the atom's electrons give or gain electrons?
Ionic bonding- the transfer of electrons from one atom to another. This results in ions, as the atoms which gain/lose electrons now have a charge.
If an atom gains electrons its electrical charge is?
Negative, assuming that the gain of electrons was an ionizing gain (not just replacing missing electrons)
What is it called when a atom that has gained or lost and electron and now has a net electric charge?
When atoms (elements) gain or loose electrons, they become Ions. If an atom looses electrons it becomes +1 charge, whereas if an atom gains electrons it becomes -1 charge.
What happenes to the charge of and atom when it gains electrons?
when atoms gain electrons they acquire negative charge
What type of charge does an atom have when it gaines an electron?
Electrons are negatively charged particles. A neutrally charged atom which gains an electron will gain a negative charge.
What describes what happens when an atom becomes an ion with a 2-charge?
An ion with a charge of 2- was an atom that lost 2 electrons to gain noble gas configuration.
How does an ion develop?
An ion is an atom with a charge. This means that the number of electrons does not match the number of protons, thus giving it a charge. If there are more electrons, it has a negative charge. If it has more protons, it has a positive charge. Remember though, an atom cannot lose or gain protons, only electrons.
What describes what happens when an atom becomes an ion with a two negative charge?
This atom gain two electrons and become an anion.
What is the gain or loss of electrons?
An electron has a negative charge. If an atom loses an electron it creates an ion with a positive charge. If an atom gains an electron it creates an ion with a negative charge.
What are charged particles when atoms gain or lose electrons?
An atom that has lost or gained electrons is known generally as an ion. More specifically, an atom that has lost electrons becomes a cation. It has a positive charge. An atom that has gained electrons becomes an anion. An anion has a negative charge.
