To create a total charge of zero, lithium with an atomic number of 3 (Li) needs to lose one electron to form Li+ with a charge of +1. Fluorine with an atomic number of 9 (F) needs to gain one electron to form F- with a charge of -1. Therefore, one atom of lithium and one atom of fluorine are needed to create a compound with a total charge of zero.

10,32 kJ are needed.
at least two
One sodium atom is needed to form an ionic bond with one sulfur atom. Sodium typically loses one electron to form a cation with a +1 charge, while sulfur gains two electrons to form an anion with a -2 charge.
Three hydroxide ions are needed to form a neutral ionic compound with an aluminum ion. Aluminum has a charge of +3, while hydroxide has a charge of -1 per ion. Therefore, the formula Al(OH)3 is needed for a neutral compound.
2 cl are needed
It is not possible to charge a phone using lemons directly. Lemons can generate a small amount of electricity, but it is not enough to charge a phone. Specialized equipment is needed to convert the lemon's energy into a usable form for charging electronic devices.
To create a total charge of zero, lithium with an atomic number of 3 (Li) needs to lose one electron to form Li+ with a charge of +1. Fluorine with an atomic number of 9 (F) needs to gain one electron to form F- with a charge of -1. Therefore, one atom of lithium and one atom of fluorine are needed to create a compound with a total charge of zero.
Two potassium ions are needed to bond with one phosphate ion to form a stable ionic compound. The potassium ions have a +1 charge and the phosphate ion has a -3 charge, requiring three +1 charges to balance the -3 charge of the phosphate ion.
84 TD's are needed
Bromine has -1 charge and Lithium has +1 charge. Therefore,only one lithium ion is required to react with a bromine ion.
5 VDC the same as all devices that can be charge from your USB port on your computer..
