Electron orbitals or shells are also called and abbreviated as?​
umka21 [38]

Answer:

An Orbital is best described as the volume of space in which electrons are most often found

Explanation:

As we know atom consists of sub-particles commonly known as protons, neutrons and electrons. The outer space around the nucleus where the probability of finding electrons is maximum is known as orbital. As the electrons are not precisely ordered around the nucleus hence it is not easy to tell the exact position of an electron.

                Hence, four quantum numbers are used to locate the position of electrons around the nucleus.

  i) Principle Quantum Number:

                                                   This number explains the main energy level which tend to increase in energy as the distance of electrons from nucleus are increased. Principle Quantum Numbers are integer number ranging from one to infinity. Hence, increase in this quantum number results in increase of the size of orbital.

  ii) Azimuthal Quantum Number:

                                                     This Quantum Number explains the direction of particular orbital in 3-dimensional space. Also it is responsible for the shape of an orbital.

 iii) Magnetic Quantum Number:

                                                      This Quantum Number also tells the direction of orbital in 3D space with respect to x, y and z axis.

 iv) Spin Quantum Number:

                                              This Quantum Number tells about the spin direction of an electron about its axis which may be clockwise or anticlockwise.

A student did not read the direction to the experiment properly and mixed up where to place the NaOH solution and the vinegar. H
Mariana [72]

Answer:

At end point there will a transition from pink to colorless.

Explanation:

As the student put the vinegar in the titrator and NaOH in the beaker, it means that he has poured phenolphthalein in the NaOH solution.

The pH range of phenolphthalein is 8.3-10 (approx), it means it will show pink color in basic medium.

So on addition of phenolphthalein in NaOH the solution will become pink in color.

When we start pouring vinegar from titrator neutralization of NaOH will begin.

On complete neutralization , on addition of single drop of vinegar the solution will become acidic and there will be complete disappearance of pink color solution in the beaker.
