They attract each other.
The electron is the subatomic particle with a negative charge.
a formal 1 negative
it has no chrage 0 (electrical)
A negative change.
Calcium has a chrage of +2 or two positive charges
no
When another charge is added to the system, the electric field due to the first charge will be affected. The electric field will combine or interfere with the new charge's field, resulting in a new overall electric field in the region. The strength and direction of the electric field at a point will be determined by the superposition of the fields due to each individual charge.
I usually charge about 50$ a device (recpt, switch, light... ect) that's if they pay for the material. about 85$ per device with material included. Or chrage out about 30-40 an hour depending on the job.
Platinum (with a chrage of +4) and Phosphorous (with a charge of -3), together in this equation they form Platinum(IV)Phosphide.
It generates electricity to chrage the automobile battery.
Depending on the voltage, about 1 hour.
Because they are either losing or gaining an electron
