You wouldn't expect strontium to gain electrons in a chemical change.
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.
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)]
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.
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
The gain and/or lose of electrons.
Atoms gain a charge by either gaining or losing electrons. When an atom gains an electron, it becomes negatively charged, while losing an electron makes it positively charged. This imbalance in the number of protons and electrons leads to the atom having a net charge.
Elements gain a positive charge when they lose electrons, not gain them. This is because losing electrons reduces the negative charge in the atom, leading to an overall positive charge.
If an atom gains electrons, it becomes negatively charged.
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.
An atom that carries a charge is called an ion. Ions can be positively charged (cations) if they lose electrons, or negatively charged (anions) if they gain electrons.
when atoms gain electrons they acquire negative charge
Electrons are negatively charged particles. A neutrally charged atom which gains an electron will gain a negative charge.
An ion with a charge of 2- was an atom that lost 2 electrons to gain noble gas configuration.
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.
This atom gain two electrons and become an anion.
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.
