It's actually called 'electronegativity'. It attracts electrons.

∙ 12y agoElectronegativity
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).
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.
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.
Yes it is small, but the power is large.
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.
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.
Power Holding Company of Nigeria was created in 1972.
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.
NADH and FADH2 are electron carriers. They are said to have reducing power because they donate electrons to components of the electron transport chain.
Since there might be problems with the specimen preparation.
A transmission electron microscope.
