What are the small superscripts representing in an electron configuration?
Wiki User
∙ 13y ago
To use the example of helium, which has theelectronic structure 1s2. The 1 refers to the orbital number (1, 2, 3 etc, also known as the principal quantum number), the letter refers to the orbital type (s, p, d, f which corresponds to the azimuthal quantum number), and finally the superscript 2 refers to the number of electrons in that orbital.
So for helium's 1s2 we have 2 electrons in the 1s orbital (filling it).
Another example could be atomic iron which has the [Ar] 3d6 4s2 configuration. This is the argon electronic structure (1s2 2s2 2p6 3s2 3p6), and then 6 electrons in the 3d orbitals, and 2 electrons in the 4s orbital as well.

Is the universe an electron?
An electron is very small. So small that you cant even see it with an electron microscope (because it uses electron to detect itself). It's mass is tiny. Billions of times less than a kg. It's just one type of matter. Some estimates put the number of electrons in the universes at greater than 10100. So no, the universe is not an electron.
The work done to move one electron in a light bulb is very small?
Yes it is small, but the power is large.
Why sulphur have higher negative electron affinity than oxygen?
Due to small size and high electron density of oxygen compared to sulphur, interelectronic repulsion is higher in oxygen, resulting in less energy being released when an electron is added to oxygen, due to lesser stability after electron is added, which is due to the interelectronic repulsion in the small oxygen atom. Hence electron affinity value is lower. It is an abnormality and exception to the general periodic trend of electronic affinity values.
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 the weight of an electron?
The mass of an electron is 9.109 382 15(45) × 10-31 kilograms (Kg). On Earth the weight of an electron is the mass times gravity. That is about 8.9278 x10-30. As a note, due to Newton's Second Law, which states F=ma, that is also the force of an electron of 1 Coulomb.

How small is a electron?
An electron is 1836 times smaller then a proton.The mass of an electron is 9,10938291(40)×10−31 kg.
Is an electron bigger then an atom?
No. An electron as a particle is small however the probability cloud of an electron can be large- most of the volume of an atom consists of the electron cloud. In relation to this the nucleus, although it contains nearly all of the mass of the atom, is quite small.
What is the particle size of a electron?
Very small...very small indeed.
Describe the octet rule in terms of noble-gas configurations and potential energy?
"Noble gas configuration" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the periodic table (in brackets). For example, the noble gas configuration of oxygen is [He]2s22p4
Is a 360 dodge engine a big block?
No. It is a small block configuration.

What are small particles that carry negative charges?
Electron
Why you need to use a electron microscope to examined a virus?
because viruses are very small and can not seen by any light microscope.only electron microscopes that use electron radiation that have wavelenght about .005 nanometer have enough resolving power to detect such a small particles as viruses
