An electric field is always present around?
an electron
Can the exact location of an electron be known at any time y?
The exact location of an electron can not be known. Electrons' locations can be merely estimated. Electron "clouds" or orbitals are general areas where an electron is likely to be found. There is always uncertainty as to where the electron actually is.
What the difference between positive and negative electrons?
an electron always has a negative chargea positron is identical in all respects to an electron (sometimes it is called a "positive electron"), except it always has a positive charge and is antimatter (not matter)If an electron and a positron meet they will both cease to exist (annihilation) and gamma ray photons will be created.
What is the work done by the field of a nucleus in a complete circular orbit of the electron. what if the orbit is elliptical?
Work done is always zero, whatever be the shape of the orbit because electron will be in the same energy state after it completes an orbit
Why can an atom lose electrons easily?
Atoms do not always lose electrons. Electrons can be gained too. Atoms always try to have their outer most shell filled, and some atoms such as ones of potassium can easily lose an electron rather than gain an electron. So it would lose an electron to a different atom so that it would have a full outer shell and the other atom would also have a full outer shell.
The internal disk-shaped sacks of membrane seen in electron micrographs of chloroplasts and surrounding a space are called?
The answer is "thylakoids"
What is hoopz race?
blackandwhite
What has the author Dorothy Ransom written?
Dorothy Ransom has written: 'The experimental use of electron micrographs as a supplement to the Rorschach ink blot technique' -- subject(s): Rorschach Test
The specimen for an electron microscope is always?
the specimen for electron microscopy is always killed
What color is a nuclear membrane?
It has no actual color. What is seen in micrographs are just light and dark.
Is a valence electron the same thing as a electron?
Yes, but valence electrons are always in the outer electron shell of an atom.
Why was martin Luther king jr locked up?
we dont know but he did go for the people who needed justice-by 13
Which would you see only in the relaxed electron micrographs of a relaxed skeletal and muscle fiber and a fully contracted muscle fiber?
This question is confusing. Are you asking if you see only a relaxed muscle fiber in EMs? Yes, you would only see that, not a contracted muscle fiber. The preparation could only be of a relaxed fiber.
An electric field is always present around?
an electron
What electron in a - sub shell experiences the greatest effective nuclear charge in a many electron atom?
The electron(s) in the 1s sublevel will always experience the greatest force, because they are always the closest and the force increases as the distance decreases.
