The compound is neutral; the ions are Al(3+) and (NO3)-.
State of Charge
Three conditions that can determine a semimetal's conductivity are band overlap, charge carrier concentration, and mobility of charge carriers. Band overlap refers to the overlapping of the valence and conduction bands, charge carrier concentration relates to the number of available carriers, and mobility of charge carriers refers to how freely the carriers can move through the material.
The atomic radius depends on the the number of electron shells, total negative charge, positive charge of the nucleus, atomic mass.
To determine the oxidation state in a complex, you analyze the charges on the ligands and any known overall charge of the complex. The sum of ligand charges and the complex overall charge should equal the total charge of the complex. From this, you can deduce the oxidation state of the central metal ion.
To determine the charge of an atom, you count the number of protons in the nucleus. This number represents the positive charge of the atom, as protons are positively charged particles.
To determine the charge density in a given system, you can divide the total charge by the volume of the system. This will give you the charge density, which represents the amount of charge per unit volume in the system.
To determine the linear charge density of a rod, divide the total charge on the rod by the length of the rod. Linear charge density is measured in coulombs per meter.
To determine the surface charge density of an object, you can divide the total charge on the object by its surface area. This will give you the amount of charge per unit area on the object's surface.
To determine the charge on a capacitor, you can use the formula Q CV, where Q is the charge, C is the capacitance of the capacitor, and V is the voltage across the capacitor. By measuring the capacitance and voltage, you can calculate the charge on the capacitor using this formula.
Electroscope can detect the presence of charge but cannot determine whether it is positive or negative because it simply detects the presence of charge, causing the leaves to either repel or attract. To determine the type of charge, additional methods such as bringing a known charged object close to the electroscope are needed to observe the interactions.
To determine the sign and value of the charge on a polyatomic ion, you need to look at the sum of the charges of the atoms that make up the ion. The charge is usually indicated in the chemical formula of the ion. If the ion has gained electrons, it will have a negative charge, and if it has lost electrons, it will have a positive charge.
To determine the charge of a body using an electroscope, place the body near the electroscope's metal cap. If the electroscope's leaves repel each other, the body has the same charge as the electroscope. If the leaves collapse, the body has the opposite charge.
To determine the charge density from an electric field, you can use the formula: charge density electric field strength / (2 epsilon), where epsilon is the permittivity of the material. This formula relates the electric field strength to the charge density of the material.
To determine the effective nuclear charge (Z effective) of an atom, you can subtract the number of inner shell electrons from the atomic number of the element. This gives you the net positive charge experienced by the outermost electrons, which is the effective nuclear charge.
Yes, an electroscope can determine if an object has a charge, but it cannot distinguish between a positive or negative charge. If the object causes the electroscope's leaves to diverge, it indicates the presence of a charge on the object. Further experiments or additional methods are required to determine the polarity of the charge.
