In diamond, each carbon atom forms 4 strong covalent sigma bonds with other carbons, resulting in a tetrahedral 3D arrangement of atoms where all the electrons are fixed in place or localised. In graphite...

Sodium and Magnesium are both metals, when they are solid they form a metallic lattice held together by the electrostatic force of attractive between the positive metal ions, and the negative delocalised ...

So if we think about a molecule of ammonia, NH3, there are 3 hydrogens, each with 1 electron (as its atomic number is 1) covalently bonded to 1 nitrogen atom with 5 outer shell electrons on it due to its ...

In atoms, electrons arrange in different shells (K, L, M...), each holding a number of orbitals (s, p, d, f...). Each orbital holds a maximum of 2 electrons. In some circ...

The cental atom in each of these molecules is C, N and O respectivly, of these both N and O are members of the family of three atoms that can form hydrogen bond (also incluidng F), when directly bonded to...
