The shape of a molecule only describes the arrangement of bonds around a central atom. The arrangement of electron pairs describes how both the bonding and nonbonding electron pair are arranged.
For example, in its molecular shape, a water molecule is describes as bent, with two hydrogen atoms bonded to an oxygen atom. However, the arrangement of electron pairs around the oxygen atom is tetrahedral as there are two bonding pairs (shared with the hydrogen) and also two nonbonding pairs.
Type your answer here...
they are the same. Lone pair is unshared pair of electrons and bond pair is shared pair of electron.
Q No. 3: (a) How MMU is used to address the physical and logical cache arrangement? Explain the difference between Least recently used and least frequently used replacement algorithm.

Chlorine has one more electron then sulfur, so it has 1 more electron in the outer shell, 1 more valence electron. Chlorine has 5 electrons in the outermost shell and sulfur has 4.
A light microscope uses visible light to magnify and view specimens, offering lower magnification and resolution compared to a scanning electron microscope (SEM) which uses a focused beam of electrons to image the sample, providing higher magnification and resolution. SEM can produce 3D images of the sample surface while light microscopes typically provide 2D images.
The molecules in a solid are bonded together permanently. Liquid molecules, on the other hand, also have bonded molecules but they continuously break and reform with other molecules. Gas molecules are not bonded.
Hydrogen is an element, the electron is a subatomic particle.
It has a different amount of space between molecules.
A principal difference between solid phases is the crystal structure, or arrangement, of the atoms
an electron
molecules
electrophiles are the electron deficient species whereas nucleophiles are the electron rich specie .the other difference is that electrophiles are the electron loving species and nucleophile are electron hating.
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
I think you're talking about nonpolar covalent molecules. These molecules share their electrons equally between atoms.
the molecules required by our body in small quantity is kown as macro molecules
