What is the net charge of a system with electron and neutron?
An electron has a charge of -1.6 x 10 (to the negative 19th power) C The neutron has no charge at all. Thus the net charge is that of the electron. -1,6 x 10(-19th power).
Why is the sodium atom smaller than the chlorine atom in a salt molcule?
The sodium atom loses an electron to chlorine. Chlorine has a higher electronegativity so it attracts the electron from sodium. Sodium now has 11 positive protons holding only 10 electrons whereas chlorine has an extra electron to control. Chlorine has 17 protons holding 18 negative electrons, therefore, its proton to electron ratio has gone down. Sodium's proton to electron ratio went up, therefore, the electrons are closer to the nucleus and the ionic radius is less than the atomic radius.
What is the charge of the electorn?
The charge of neutron is 0, as it is neutral. The charge of proton is 1.6x 10 to the power -19 coulomb. The charge of electron is -1.6x10 to the power -19 coulomb.
The work done to move one electron in a light bulb is very small?
Yes it is small, but the power is large.
Would you use a stereomicroscope or compound light microscope or electron microscope to see a virus?
A virus of 50nm would be too small to see unless an electron microscope was used because it has greater resolving power and a resolution up to .1nm. A microscope using compound light as the means of illumination could not resolve better than approx. 200nms.
What is a quantum number?
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
When was Power Holding Company of Nigeria created?
Power Holding Company of Nigeria was created in 1972.
What is the power source of a electron microscope?
The power source of an electron microscope is an electron gun located in the microscope that fires electrons through a series of lens and into a non-living object.
What does NADH and FADH2 power?
NADH and FADH2 are electron carriers. They are said to have reducing power because they donate electrons to components of the electron transport chain.
What limits the resolving power of an electron microscope?
Since there might be problems with the specimen preparation.
Which has the least resolving power?
A transmission electron microscope.
What is the net charge of a system with electron and neutron?
An electron has a charge of -1.6 x 10 (to the negative 19th power) C The neutron has no charge at all. Thus the net charge is that of the electron. -1,6 x 10(-19th power).
Which microscope has the greatest magnifying power?
Transmitting Electron microscope has the greatest magnifying power.
Does an electron microscope need electricity?
Yes, an electron microscope cannot operate without a source of electrical power.
Can we observe living organisms in an electron microscope?
No - because the power generated by the electron beam destroys any living tissue.
Can you generate the electricity by the moving of proton as electron?
No. While the proton has the opposite charge of the electron, the proton will not flow from atom to atom like the electron does because the strong atomic force holding the proton in the nucleus is much more powerful than the electromagnetic force.
Why is the sodium atom smaller than the chlorine atom in a salt molcule?
The sodium atom loses an electron to chlorine. Chlorine has a higher electronegativity so it attracts the electron from sodium. Sodium now has 11 positive protons holding only 10 electrons whereas chlorine has an extra electron to control.
