What is the principal reason we must consider the uncertainty principle when discussing electrons and other subatomic particles
Pie
Here is the correct answer of the given question above. The principal reason that we must consider the uncertainty principle when discussing electrons and other subatomic particles, but not when discussing our macroscopic world is that photons of only certain allowed frequencies can be absorbed or emitted as the electron changes energy state. Hope this answer helps.

Which compound contains both covalent and ionic bonds kcl nh4cl mgcl2 ccl4
Vedmedyk [2.9K]
The answer is NH4Cl!
Ionic bonding=cation + anion
- the cation ammonium (NH4) has a single electron in its valence shell, and Chlorine needs a single electron to fill its valence shell, and they stick together.
Covalent bond= involves the sharing of electron pairs between atoms
- present in Ammonium ion between Nitrogen and Hydrogen atoms

How is graphite different from other allotropes of carbon?
vladimir1956 [14]

B) The carbon atoms in graphite are arranged in widely spaced layers

Explanation:

Graphite is different from other allotropes of carbon because the carbon atoms in graphite are arranged in widely spaced layers. Graphite and diamond are the two main allotropes of carbon that are closely related.

  • Both allotropes forms under extreme temperature and pressure. In geology, they are categorized as derivatives of changed rocks.
  • Graphite is different from carbon because its atoms are arranged in widely spaced layers.
  • Diamond has a packed and cross-linked structure that makes it rigid and very hard.

How does the number of substituents around a central atom affect the shape of a molecule?
SSSSS [86.1K]

Explanations:- The shape of the molecule depends on bonding groups and lone pair of electrons present in the central atom. We do the sum of these bonding groups and lone pair of electrons for the shape of the molecule. The presence of lone pair of electrons affects the shape (molecular geometry) of the molecule.

For example, methane is tetrahedral as four hydrogen atoms are bonded to carbon and there is no lone pair of electrons present on C. Here, the sum of bonding groups and lone pairs is 4.

On the other hands, in water, two H atoms are bonded to the central oxygen atom and also there are two lone pair of electrons present on oxygen atom. The sum is also 4 here but the molecular geometry is bent. The difference in geometries of these two molecules is because of the repulsion between the two lone pairs present on oxygen atom.

If we take an example of boron hydride then three H atoms are bonded to B and there is no lone pair of electrons present on B. The sum is 3 and so it's shape is trigonal planar.

So, the number of bonded atoms as well as the number of lone pairs present on the central atom decides the shape of the molecule.
