1st Shell: 2 2nd Shell: 8 3rd Shell: 8
A shell of an atom is meant to contain or hold an electron floating around the nucleus. They don't actually cover the whole atom. They're rings made of the electrons that float in orbit around the atom.but the answer is electron paths
No. Only the electrons in the outer most shell take part in chemical reactions.
The average atomic mass of an element would be closer to a whole number if there were few to no electrons. This means having little to no electrons in the element's isotopes.
Tin's atomic number is 50. Thus, neutral tin has 50 protons and 50 electrons. The first 50 orbitals are filled as 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p2. Thus, tin has 4 valence electrons and 46 inner-shell electrons.
The term valance shell refers to the number of electrons in the outermost orbit so by taking that we can consider hydrogen has no valance electrons because the hydrogen atom has only two electrons and the first electronic orbit can hold that much number of electrons in it.

There are 7 Energy Levels of electrons called shells, and there are 4 sub-shellsnamed as sub-shells s, p, d, and f. They are ordered as 1s - 2s - 2p - 3s- 3p - 4s - 3d - 4p - 5s- 4d - 5p - 6s - 4f - 5d - 6p - 7s - 5f - 6d - 7p - 6f - 7d - 7f. "s" sub-shells consists of 2 electrons, "p" sub-shells consists of 6 electrons, "d" sub-shells consists of 10 electrons, and "f" sub-shells consists of 14 electrons. The first shell has 2 electrons, the second shell has 8 electrons, the third shell has 18 electrons, the fourth shell has 32 electrons, the fifth shell has 50 electrons, the sixth shell has 72 electrons, and the seventh and last shell has 98 electrons. Oh!!! By the way, the formation of the energy levels is like the solar system. The sun is the nucleus and the proton while the Planets are the electrons. There are seven orbits and each orbit has its own electron count. I mentioned it earlier in this answer of mine.
No. Only the electrons in the outer most shell take part in chemical reactions.
It is the maximum of that set.
The simply answer is that in the outer shell each of the halogens have only seven electrons, this is the reason why they are the most reactive nonmetals, they wish to require a further electron to become stable. Fluorine (F) Atomic number 9 [He] 2s22p5 note the second shell is the outer shell and has only 7 electrons, to be stable it has to have eight. Chlorine (Cl) Atomic number 17 [Ne] 3s23p5 note this its the third shell which is the outer shell and has only 7 electrons, to be stable it has to have eight. For Bromine (Br) we find its the fourth shell is the outer shell which has seven elections, and finally Iodine (I) we find its the fifth shell which is the outer shell and it has only 7 electrons, to be stable it has to have eight. Hope this helps

india has the maximum number of jain's in the whole world

Number of protons = atomic number Number of neutrons = Atomic Mass (rounded to the nearest whole number) minus the atomic number Number of electrons in a stable element = number of protons Number of electrons in an unstable element = atomic number minus the charge
