More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
The happy atoms are the noble gases. They don't react because their valence electron shells are full. The goal of every element is to have the most outer shell of electrons full. The first shell holds 2 electrons, and every shell after that holds 8 electrons. So helium and hydrogen both want to have 2 electrons in their outer shells. Elements like neon and argon have 8 electrons in their outer shells. Atoms like chlorine and fluorine have 7 electrons in their outer shells. This means that aren't "happy" because they want to have 8. This is why they ionically bond with atoms like sodium that have 1 electron in their outer shells. Sodium gives that electron to chlorine and now both have 8 electrons in their outer shells.
the no. of electron shells in an atom varies for every element in the periodic table, depending on its no. of electrons in the atom. the no. of shells of an atom of an element ca be derived through the period of the periodic table. elements in the 1st period has only 1 shell and so forth.
electrons surround the nucleus of an atom in layers are called shells
electron configuration :)
true
These atoms are very stable and unreactive.
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
Atoms bond because they "share" their electrons. Every atom wants to have 2 atoms in their first shell, and then 8 in all the other shells. Lets say we have an atom with 3 electrons, and one with 9 electrons, they will esaly bond

In atoms, whenever energy is supplied to it an electron or the required group of electrons traverses to higher level shells.
Atoms with outer electron shells that contain 8 electrons tend to be stable and chemically in reactive, or inert.
Electrons are located in the electron cloud - no joke. Atoms are composed of the electron could and the nucleus.

Generally yes, as long as there are 6 electrons in the electron shells. Carbon rarely carries a charge.
Metals tend to form positive ions because their electron structure causes them to do so. We need to talk briefly about what this means, so put on your thinking cap and grab a seat. We know that electrons form up around atoms in shells (energy levels). And only a certain number of electrons can occupy a given shell. Further, atoms tend to want to have outer electron shells that are filled to capacity, just like the inert or noble gases. To that end, atoms will loan out or borrow electrons, and this is the basis for chemical bonding. Metals are atoms that have incomplete outer electron (valence) shells. But they are also atoms that have a lot fewer electrons in their outer shell than it takes to actually fill that shell. (This is in contrast to the nonmetals, which have outer electron shells that are nearly full.) Because metals have "so few" electrons in their valence shells compared to what it would take to fill them, it is "easier" for these atoms to loan out electrons rather than borrow electrons to reach a point where they are emulating an inert element. Because metals loan out electrons to reach a point where they are "like" inert gases, they will end up as positive ions. And this is why metals form positive ions.
The distribution of electron around an atom in various shells is sometimes referred to as electron cloud. If there are more electrons in certain space around the atom, that space is said to have a denser electron cloud.
