If Na was to form a 2 ion, from what orbital subshell would the second electron be lost?

Chemistry
1 answer:

3 0

Answer:

2p

Explanation:

Sodium has an atomic number of 11, thus, the neutral atom has 11 electrons. The electron configuration is:

Na: 1s² 2s² 2p⁶ 3s¹

To gain stability, it loses an electron from its outer shell to form the cation Na⁺. Its electron configuration is:

Na⁺: 1s² 2s² 2p⁶

If it were to lose a second electron to form a Na²⁺ cation, the electron should be lost from the 2p orbital subshell and its electron configuration would be:

Na²⁺: 1s² 2s² 2p⁵

From the image shown, the uncertainty in the weighing balance extends to the hundredth place.

<h3>What is a balance?</h3>

A balance is any device that is used for measuring the mass or weight of an object. The balance is a necessary instrument in every laboratory.

Looking at the image shown, the following are true;

  • the uncertainty is in the hundredth place.
  • a mass that falls between 1 gram and 9 grams measured on this balance will always have 3 significant figures.

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.
