Why does hydrogen only have 1 electron in the outer shell?
To balance the charge of the single proton in the nucleus.
What is an alternative method to measure the charge to mass ratio of an electron?
Modern Mass Spectrometry is the alternative method to measure the charge to mass ratio of an electron.
Do electric charges always exist in whole number multiples of a single basic unit?
Yes they do. The basic 'quantum' of charge is the amount ofnegative charge on one electron, and also the amount ofpositive charge on one proton. The amount is0.000 000 000 000 000 000 160 217 646 Coulomb
How much electrial charge does an electron carry?
1.6 x 10-19 coulombs
Why do cathode rays move from the negative end of the tube to the positive end?
Because an electron carries a negative charge and in electricity, opposites attract. Particles with a negative charge will be drawn to the positive charge in the cathode tube.
Who determined the charge of a single electron?
my boy democritis aka d-crit and his brother jj "money" thomson
How many faradays of charge does a single electron have?
There is less than one faradays of charge in a single electron. It takes thousands of electron to charge anything and only either protons or neutrons are capable of charging a single electron.
A single unit of neg charge is a?
electron
How many electrical charges are in protons?
A proton has single positive charge neutrons have no charge and a electron has a single negative charge
How calculate electrons?
To calculate the number of electrons, you need to know the total charge of the system or material in question and the charge of a single electron (approx. -1.6 x 10^-19 coulombs). By dividing the total charge by the charge of a single electron, you can determine the number of electrons. Formula: Total number of electrons = Total charge / Charge of a single electron.
What did Robert milikan discover?
Millikan's oil-drop experiment demonstrated that charge is quantized, and that the quantum of charge ... the 'elementary' charge ... is 1.6 x 10-19 Coulomb.
A physicist who determined the chare of an electron by means of his oil-drop experiment?
There are two scientist working together: The oil drop experiment was an experiment performed by Robert Millikan and Harvey Fletcher in 1909 to measure the charge of the electron (the elementary electric charge).
What is the smallest amount of excess charge that a tape could possibly have?
The smallest amount of excess charge that a tape could possibly have is the charge carried by a single electron or proton. The charge of a single electron is approximately -1.6 x 10^-19 coulombs.
How does a coulomb of charge compares with the charge of a single electron?
the charge of 1 coulomb is the charge associated with 6.25 billion billion electrons
What is the ionic charge of fluoride ion?
It is a single negative charge, so the fluoride ion is denoted F-. The fluorine atom gains one electron to incur a single negative charge of -1.
Is an electron made of a single element?
The electron is not a chemical element: it is a small elementary particle with a negative electrical charge.
Who discovered the charge to mass ratio for the electrons?
Millikan found the charge of an electron by his famous oil drop experiment. J J Thomson determined the specific charge of the electron. That means the ratio of the charge of an electron to its mass. With these two values one can find the mass of electron by dividing the charge value by its specific charge.
