O that is oxygen is a non metal and a non metal has a characteristic of gaining electrons so when they gain electrons the also gain a net charge in negative as no. of protons become less than the no. of electrons. now oxygen has atomic no. 8 and valency of 2 so it requires 2 electrons to complete an octet i.e. 8 electrons in the outermost shell and to get a negative charge. since it will gain 2 electrons so it will have a net charge -2. The oxidation number of oxygen is -2, except in a few cases, including superoxides (-1/2), peroxides (-1), and oxygen fluorides (+1, +2).

Why 1 is using as on state in binary language?
Computers are built off of electronic circuits, in which there is either no voltage or there is some positive number (usually 3.3V, 5V or 12V). 1 represents an electric charge while 0 represents no charge.
What is indicator variable?
It is a variable that takes the value 1 if the characteristic under consideration is present and 0 otherwise.
What is characteristic equation in control systems?
Set 0=(denominator of the System Transfer Function), this is the Characteristic Equation of that system. This equation is used to determine the stability of a system and to determine how a controller should be designed to stabilize a system.
What is a Variable 0 - 12V dc power supply?
A variable power supply has a control to adjust the DC output voltage from 0 to 12 volts. It is used for testing electric project's such as amplifiers and other electric devices. It can be used to replace other fixed voltages power supplies such as the srandard 3 volt, 5 volt, 9 volt and 12 volt units.
What is the characteristic impedance of free space and why do you think so?
Characteristic impedance (Z0) is defined as E/H ratio of {E,H} field. It depends on dielectric permettivity (epsilon), magnetic permettivity (mu) and geometry of region in which {E,H} propagates. For free space, it's easy to believe that geometry coefficient is 1 and in the end, you get -> Z0= square root (mu 0 / epsilon 0) = 120 pi, where subscript 0 means mu and epsilon referred to free space and pi=3.14... If you want to demonstrate that, you have to solve Maxwell's equation, imposing the condition of uniform plane wave travelling into free space, so you'll get an Helmholtz equation for Coulomb electric potential phi (you have to apply Lorentz's gauge condition and you'll get laplacian(phi) + k^2 phi = 0, where k=2*pi*frequency/c0 is called wave number). You solve this equation and put it into the equation linking magnetic potential vector (A) and phi. At this point, you can solve Maxwell equations and get E,H values and modulus ratio (Z0).
What is the electric charge on the ion in the compound calcium oxide?
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
What is the electric charge on the calcium ion in the compound calcium oxide?
The electric charge on the calcium ion in calcium oxide is 2+. This is because calcium (Ca) forms a cation with a charge of 2+ when it loses two electrons to achieve a stable electronic configuration.
What is the charge on the copper ion in Cu3P?
The charge on the copper ion in Cu3P is +1. This is because the overall charge for the compound Cu3P is 0, and since there are three copper ions present, each copper ion must have a charge of +1 to balance the -3 charge of the phosphorus ion.
What is the charge on CrCl3?
The charge on CrCl3 is 0, since it is a neutral compound. Each Cl ion has a charge of -1, meaning that three Cl ions combine with one Cr ion with a charge of +3 to form the compound with an overall charge of 0.
Does BeF2 have a 3 charge?
No, BeF2 does not have a 3 charge. Beryllium fluoride (BeF2) is a neutral compound with a 2+ charge on the beryllium ion and a 1- charge on each fluoride ion, resulting in a net charge of 0.
What is the charge of sodium hydroxide?
Sodium hydroxide has a charge of +1 on the sodium ion and -1 on the hydroxide ion, resulting in an overall charge of 0 for the compound.
How many potassium ions are needed to balance the charge of one sulfide ion Explain?
One potassium ion is needed to balance the charge of one sulfide ion. This is because potassium has a +1 charge and sulfide has a -2 charge. Therefore, one potassium ion with a +1 charge will neutralize the -2 charge of one sulfide ion, resulting in a net charge of 0.
What is the charge of a carbonate ion in sodium2 cobalt3?
the charge is 4 2+C+3(-2)=0 C=4
What is The formal charge on the carbon atom in the carbonate ion?
the formal charge of carbon in carbonate ion is 0solutionvalence electron-4non bonded electron-0and total no of bonding electrons=8formal charge = valence - non bonded - 1/2 total number of bonding electronselectron electron= 4-0-4= 0
What is the charge of Mn?
Fluoride ions have a charge of -1, so three fluoride ions have a total charge of -3. Since there is only one manganese ion in the formula, the manganese ion has to have a charge of +3, so that the overall charge is 0.
What is the formal charge for H3S?
Such an ion would most likely carry a 1+ charge.
What is the charge of silver nitrate?
Silver Nitrate-- AgNO3 has no charge since Ag (silver ion) has a +1 charge and NO3 (nitrate, a polyatomic ion) has a -1 charge [1+(-1) = 0]. Most chemical compounds are usually balanced.
