If it had more than two electrons it would no longer be hydrogen.
Hydrogen and chlorine can form a molecule with a single covalent bond, creating the compound hydrogen chloride (HCl). The two nonmetals share one pair of electrons to achieve a full outer shell configuration.
Because its outer shell is full of electrons and cant attract anymore to become a negative ion. It cant become a positive ion because it has 8 electron on its outer shell so it would be too hard for another atom to take it
at. no of sodium= 11 k l m 2 8 1 therefore its valence shell electron = 1 at. no of chlorine=7 k l m 2 8 7 therefore its valence shell electron=7 because there are two chlorine atoms therefore 2* at. no = 2*7=14 therefore its lewis dot structure will be .. .. : Cl .. Mg .. Cl: .. ..
A third hydrogen atom cannot join an H2 molecule to form an H3 molecule because the H2 molecule is already at its lowest energy state, known as the ground state. The two hydrogen atoms in an H2 molecule are held together by a strong covalent bond, and adding a third hydrogen atom would require breaking this stable bond, which would require more energy than is available. Additionally, the formation of an H3 molecule would violate the octet rule, as hydrogen can only have a maximum of two electrons in its valence shell.
Nonmetals typically form covalent bonds when they share electrons to achieve a full outer electron shell. This type of bonding is commonly observed in molecules like H2O (water) and CO2 (carbon dioxide), where atoms share electrons to achieve stability.
because they need water
i cant answer that sorry

Cobalt has 9 valence electrons and generally cant lose 9 electrons to achieve the noble gas configuration.
you cant its inposible just pay attention in class and u will find out.
Because forming more than four bonds would give the atom more than 8 valence electrons
Group numbers tell us that how many electrons an atom contain in its outer shell. Eg. Na11 have 1 electron in its outer shell it means Na belongs to group 1. and so on.
no because it has a shell that is hard and you cant eat the shell because the shell is attached to the turtle
O(CH2)4NH you have to draw the O at the top of the ring with its two lone pairs, then on both sides is a C with two branching Hs and then continued around the hexagone like structure until you get to the bottom where you put an N with two lone pairs and a H branching off of it. Cant really draw it on here, but hope that helps!
To draw a diagram of a potassium atom with its electrons in their shells, you would start with the nucleus at the center. Potassium has 19 electrons, so you would place 2 electrons in the first shell, 8 electrons in the second shell, and the remaining 9 electrons in the third shell. Each shell should be drawn around the nucleus in concentric circles to represent the energy levels of the electrons.
