k shell has two electrons because in the structure of an atom every shell has an capacity to have fixed number of electrons that why k shell has capacity to have 2 electrons.

How many shells in lithium?
The number of electron shells in a normal Lithium atom is 2. It has an electron configuration of 1s22s1
Is the first electron shell called the L shell?
No, its called the K, then the L is after it and then the M and so on. On the periodic table, the period an element is in is how many electron shells it has.
What is the meaning of K electron shell?
K is the old symbol for the first electron shell in atoms (near the nucleus). The K shell contain max. 2 electrons.
How many electron shells woul be completely filled by a neutral xenon atom?
Your question reveals a common confusion between orbitals and shells. Chlorine has three electron shells: the first, second and third. The first shell has just the one orbital, the 1s The second shell has two sub-shells, the 2s and the 2p. There are three p orbitals in the 2p sub-shell. Each orbital can hold two electrons, so there are eight electrons maximum in the second shell. The third shell likewise has two sub-shells, the 3s and the 3p, but the 3p is not completely filled, leaving room for one more electron. When chlorine gains this electron it will become a Cl- ion. This is summed up in the electron configuration 1s22s22p63s23p5.
How many electrons does NA has in outer most shell?
there is only one electron in the outermost shell of Na.
How many electrons are on each orbit for sodium?
The atomic no. of Sodium (Na) is 11. It has three electron orbits (or Shells) containing 2, 8 and 1 electron respectively. K shell - 2 electrons L shell - 8 electrons M shell - 1 electron
Why it is calledl K L M N shells?
The letters K, L, M, N, etc. denote different electron shells in an atom. Each shell represents a different energy level where electrons are found, with K being the innermost shell and letters further in the alphabet representing shells further from the nucleus. These labels come from spectroscopic notation that identifies different energy levels in atoms.
What is the outer shell of an electron called?
The electron shell is also called the principle energy level in chemistry and atomic physics. The shells starting closest to the nucleus names go from shell 1 or shell K, shell 2 or shell L,shell 3 or shell m, etc. Each shell contains a certain amount of electrons the first shell starts with two and the number increases for each shell.
How can i convert real number to round that number?
An electron shell may be thought of as an orbit followed by electrons around an atom's nucleus. The closest shell to the nucleus is called the "1 shell" (also called "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on further and further from the nucleus. The shell letters K, L, M, ... are alphabetical.Each shell can contain only a fixed number of electrons: The 1 shell can hold up to two electrons, the 2 shell can hold up to eight electrons, and in general, the n shell can hold up to 2n2 electrons. Since electrons are electrically attracted to the nucleus, an atom's electrons will generally occupy outer shells only if the more inner shells have already been completely filled by other electrons. However, this is not a strict requirement: Atoms may have two or even three outer shells that are only partly filled with electrons. (See Madelung rule for more details.) For an explanation of why electrons exist in these shells see electron configuration.[1]
How many electrons does a boron atom have in its outer shell?
Boron has 2 orbitals
Describe the presence of sub shells in a shell?
A sub shell is an area inside an atom's electron shell that contains a type of electron orbital. Each and every atom consists of a central nucleus of one or more positive protons and zero or more chargeless neutrons, with electrons traveling about it the electrons are on shells
What is sub shell letter?
Subshell letters indicate electron shells. The letters K-Q or numbers 1-7 are called subshell letters. They are placed in superscript form.
