A spherical electron cloud surrounding an atomic nucleus best represents what?
A spherical electron cloud surrounding an atomic nucleus would best represent an s orbital. A maximum of 2 electrons can occupy an orbital.
Where is a electron located?
They are located in the electron cloud of an atom. ---------- Electrons (very low mass particles with negative electrical charge) are placed around the nucleus of an atom in electron shells, with different energy levels; because the nucleus contain protons the electrical charge is positive. The electron cloud is a model of quantum mechanics.
Why does sodium give up an electron?
because it wants to lose an electron
What law says it is impossible to determine the exact location and velocity of an electron at any given moment?
This is because of the Heisenberg uncertainty principle. It is a part of quantum mechanics. It has to do with an electron having properties of both a particle and and wave. If you only imagine an electron to be a particle, this can be somewhat explained by the process of measuring the position or velocity of the electron. If the data is measured with light, then when a photon hits the electron, it changes the electrons speed and position. We may be able to find one, but in the process, the other will be changed.
The is the particle in the nucleus with a positive charge?
The nucleus of an atom has a positive charge. This is because the nucleus contains both protons, which have a positive charge, and neutrons, which have no charge. The electrons, which have a negative charge are found in the electron cloud surrounding the nucleus.
Why is the size of a laser or electron beam measured in milliradians?
The size of a laser or electron beam is measured in milliradians. This is because they are subject to divergence.
What do you call the type of unit that can be measured directly?
There is no specific name. This is partly because derived units, such as volume, can be measured just as directly as lengths.
Motives are described as hypothetical states because?
motives are internal factors that drive behavior and are not directly observable. They are inferred based on a person's actions, emotions, and beliefs, making them hypothetical in nature. Motives can vary in intensity and can be influenced by a variety of internal and external factors.
What is the weight of a ball having density 2.86 cm and 12.6 cm volume?
It is not possible to answer the question because: density is not measured in cmvolume is not measured in cmwhile mass = density*volume, weight in not directly related to density.It is impossible to guess the correct units for density and volume. It is not possible to answer the question because: density is not measured in cmvolume is not measured in cmwhile mass = density*volume, weight in not directly related to density.It is impossible to guess the correct units for density and volume.

How many electrons are in a nitrogen particle?
There is one electron in a beta- particle, because a beta- particle is an electron and an electron antineutrino. A beta+ particle is a positron and an electron neutrino. A link can be found below to a related question that will help a bit in sorting out the puzzles surrounding beta particles.
Why is the mass of electron difficult to find?
The mass of an electron is difficult to find because of the Heisenberg Uncertainty Principle. Either a particle's position or direction can be known, and the more precisely one is measured, the other is subject to more possible variation.
Why is displacement of water an example of an indirect measurement?
Water displacement is a method to measure volume
What are the spheres surrounding the nucleus that contains an atom's electrons?
The spheres surrounding the nucleus of an atom are called protons and neutrons, protons hold the electrons in orbit around the nucleus because a proton has a positive charge which attracts the electron which has a negative charge causing electromagnetic force which holds the electron in orbit. The neutron determines the isotope of the atom but has a neutral charge.
Can two different bacteria using different electron acceptors survive on same substrate how do they compete?
Two different bacterias using different electron acceptors can survive on the same substrate because they do not compete directly.
How can an electron have mass but does not have an diameter?
It has no diameter because it is a point particle (it has nothing inside it). It has mass because the mass has been measured experimentally. If this is hard to imagine, science has lots more concepts even harder.
