How does the charge of an electron compare to the charge of a proton?
Of course, their charges are OPPOSITE in sign...........Electrons (inconveniently!) are assigned a negative charge, and protons assume a positive charge.

The ratio for an mass-to-charge electron is $5.64 x 10^(-12)$ kg/C. In another experiment, using Millikan's oil drop apparatus, the found the charge on the electron is $1.605 x 10^(-19)$ C. What would be the mass of the electron, according to these data?
And should I multiply $"mass"/cancel"charge"xxcancel"charge"$, I should get an answer of $"mass"$. Let's see: $5.64xx10^-12*kg*cancel(C^-1)xx1.605xx10^-19*cancelC$ $~=1xx10^30*kg$ for a single electron. Well, I got the units of mass, which...

What is the mass-to-charge ratio of electrons?
Chemists are more likely to talk about the charge-to-mass ratio of electrons. The charge on an electron is $1.602 × 10^"-19"color(white)(l) "C"$, and the mass of an electron is $9.109...

A particle is moving with 3 times faster than speed of electron.Ratio of wavelength of particle and electron is 1.8×10^-4 then particle is?
We use the de Broglie expression: $sf(lambda=h/(mv))$ So we can write: $sf(lambda_(e)=h/(m_(e)v_(e))" "color(red)((1)))$ $sf(lambda_(p)=h/(m_(p)v_(p))" "color(red)((2)))$ $sf(v_(p)=3v_(e)" "color(red)((3))$ Substituting $sf(color(red)((3)))$ into...

In an electron microscope, electrons are accelerated to great velocities. What is the wavelength of an electron traveling with a velocity of $7.0 *10^3$ $"km/s"$ ? The mass of an electron is $9.1*10^(-28)$ $"g"$.
You're actually looking for the de Broglie wavelength here, which, as you know, characterizes particles that have mass. The de Broglie wavelength depends on the momentum of the particle,...

Whats the difference between electron shells, electron levels, and electron orbitals?
Electron orbitals are probability areas of finding an electron in a given space. Different electron orbitals have different mathematical formulas giving different shapes and energy levels for the different electron...

A mixture of gases contains $"H"_2$ and $"O"_2$ gases in the ratio of $"1:4 w/w"$. What is the molar ratio of two gases in the mixture?
All you have to do here is to convert the mass ratio to a mole ratio by using the conversion factor that takes you from grams to moles or vice...

A compound containing only carbon and hydrogen has a carbon-to-hydrogen mass ratio of 11.89. Which carbon-to-hydrogen mass ratio is possible for another compound composed only of carbon and hydrogen?
Trying to present a possible Answer We know that the molar mass of carbon and hydrogen are $C=12"g/mol" and H = 1"g/mol"$ When Carbon Hydrogen mass ratio is 11.89 The...

Explain how carbohydrates are structured in a 1:2:1 ratio. Which atom does each number in this ratio represent?
Sugar has a formula of $C_6H_12O_6$, which, of course, has an empirical formula of $1:2:1$ with respect to $C$, $H$, and $O$, or an empirical formula of $CH_2O$.
