It is because the flow of electrons go from the object to the earth

Charging an earthed metal object would cause the charges to be quickly neutralized by the earth's conductor. Since the earth is a good conductor of electricity, any excess charge on the metal object would dissipate rapidly into the ground, preventing the object from holding a charge.

What is an object that cant dissolve in a liquid?
One example of an object that can't dissolve in a liquid is a metal spoon. The chemical structure of the metal composing the spoon does not allow it to break apart and mix with the liquid, so it remains intact.
Does radon conduct heat?
yes AS IT is a metal but why use i cant think
Why cant you get electrocuted during a thunderstorm in the car?
The metal car acts as a Faraday cage, conducting the electrical charge around the passengers inside the vehicle instead of through them. This offers protection from being electrocuted in a lightning storm while in a car.
How can you tell if metal leaf electroscope is neutral or positive?
To determine if a metal leaf electroscope is neutral, bring a charged rod near the metal cap. If the metal leaves diverge, the electroscope is neutral. If the metal leaves collapse or diverge more, the electroscope is positively charged.
Why cant you change the charge of an ion to make formulas?
You can't change the charge because that is changing the very chemical nature of the ion/atom. To make formulas with ions, you use subscripts to change the NUMBER of ions in the formula without changing the CHARGE.
What is an example of an object with a negative charge?
really, you idiots cant just bring science books home.
What is an object that cant dissolve in a liquid?
One example of an object that can't dissolve in a liquid is a metal spoon. The chemical structure of the metal composing the spoon does not allow it to break apart and mix with the liquid, so it remains intact.
How do you know if an object is metallic?
There are certain obvious characteristics of metal that once cant miss. Every metal conducts heat and electricity. All metals can be molded into wires and thin sheets.
Is a metal spoon transparent opaque or translucent?
Nope. It only reflects. Refraction is pretty much distortion.
How do you get a metal coat in emerald?
you cant
Can a gerbil get out of a metal cage?
No it cant
What is being done to protect the statue of liberty from weathering?
= The National Park Service is in charge of security at the Statute of Liberty. It screens visitors with the same kind of metal detectors used at airports, and provides guards on the island. =
What happens when your ipod touch cant charge?
you buy a new charge cable
Can you fill electric charge in earth?
no you cant
How do you get out of marijuana possession charge?
U cant
Where do you find Metal Claw on Pokemon ruby?
you cant find metal claw
Why cant determine the positive and negative charge with electroscope?
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.
