Given:
Atomic number of an atom = 14
Partial electron configuration = 1s²2s²2p⁶3s²X
To determine:
The identity of X
Explanation:
Based on the Aufbau rule, the order in which the orbitals fill up based on energetic considerations is:
1s 2s 2p 3s 3p 4s 3d 4p ....
maximum # electrons in s orbital = 2, p = 6, d = 10 and so on
Since 3p would follow the 3s orbital, in this case we will have the full configuration as:
1s²2s²2p⁶3s²3p²
Ans c) X = 3p²
Answer: Atoms of different elements are found to have different number of protons, neutrons, and electrons. To distinguish one atom from another or to classify the various atoms, a number which indicates the number of protons in the nucleus of a given atom, is assigned to the atoms of each identified element. This number is known as the atomic number of the element. The atomic numbers for some of the elements which are associated with the study of semiconductors are given in the following table.
Explanation:
Element Symbol Atomic Number
Silicon Si 14
Germanium Ge 32
Arsenic As 33
Antimony Sb 51
Indium In 49
Gallium Ga 31
Boron B 5
Thanks for the points bud
Answer:
a single d orbital can hold 10 electrons
Answer: A: Has little to no reaction; might turn slightly red in color. B: The liquid grows darker in color to a more reddish tone.
Explanation: I didn’t have the necessary materials to complete the experiment so the teacher told me and I put it in my own words.
