Explanation:
The electron configuration you provided is for the element with 3 electrons. The 2p² electron configuration would involve adding two more electrons to the 2p subshell. Let's determine the four quantum numbers (n, l, ml, and ms) for one of these 2p² electrons:
1. Principal Quantum Number (n): In this case, n is the same as the principal quantum number for the 2p subshell, which is 2.
2. Azimuthal Quantum Number (l): The azimuthal quantum number (l) represents the subshell within the principal energy level. For the 2p subshell, l = 1.
3. Magnetic Quantum Number (ml): The magnetic quantum number (ml) specifies the orientation or orbital within a subshell. For the 2p subshell, ml can take on three values: -1, 0, and 1. Since we're describing one of the two 2p² electrons, you can choose either -1 or 1 for ml.
4. Spin Quantum Number (ms): The spin quantum number (ms) represents the spin of the electron. It can have two values: +1/2 (spin up) or -1/2 (spin down). You can choose either +1/2 or -1/2 for ms.
So, one possible set of quantum numbers for one of the 2p² electrons could be:
n = 2
l = 1
ml = 1 (or -1)
ms = +1/2 (or -1/2)
You can choose either ml = 1 and ms = +1/2 or ml = -1 and ms = -1/2 for one of the 2p² electrons, as long as the other electron in the same orbital has the opposite spin.
The quantum numbers of an electron in the 2p orbital with the electron configuration 1s² 2s² 2p¹ are principal quantum number (2), azimuthal quantum number (1), magnetic quantum number (-1, 0 or 1) and spin quantum number (+1/2 or -1/2). These numbers represent the energy level, orbital shape, orbital orientation and electron's spin respectively.
The electron configuration expressed as 1s² 2s² 2p¹ represents how electrons are distributed in an atom's atomic orbitals. Examining this, it indicates that there are two electrons in the 1s orbital, two electrons in the 2s orbital, and one electron in the 2p orbital. The four quantum numbers of the electron in the 2p orbital are principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l), and spin quantum number (m_s).
The principal quantum number (n), denotes the energy level the electron is in, in this case, 2.
The azimuthal quantum number (l), also, known as the orbital quantum number indicates the shape of the orbital, for a 'p' orbital, l = 1.
The magnetic quantum number (m_l), describes the orientation of the orbital - this can have any value from -l to +l. For a 'p' orbital, m_l could be -1, 0, or 1, representing the three 'p' orbitals, 2px, 2py, and 2pz respectively.
Finally, the spin quantum number (ms) will be either +1/2 or -1/2, representing the two possible spin states of an electron.

76 In the space in your answer booklet, draw a Lewis electron-dot diagram for the compound that tarnishes silver. [1]
77 In the ground state, an atom of which noble gas has the same electron configuration as the sulfide ion in Ag2S? [1]
Silver tarnishes due to the chemical reaction with hydrogen sulfide, forming silver sulfide. A Lewis dot structure for H2S shows sulfur at the center bonded to two hydrogen atoms. The sulfide ion in Ag2S has the same electron configuration as the noble gas neon.
The chemical compound that tarnishes silver is hydrogen sulfide, H2S. In terms of Lewis electron dot structures, hydrogen sulfide, H2S, would be modelled as an S atom at the center surrounded by two H atoms. Each H atom is bonded to the S atom by a shared pair of electrons, represented by a single line. In the sulfide ion S2- (which is a part of Ag2S), there are additional 2 electrons to the sulfur atom, making a total of 8 valence electrons, which is the same electron configuration as the noble gas neon.

The compound that tarnishes silver is silver sulfide (Ag2S), and its Lewis electron-dot diagram can be drawn by representing the valence electrons. The sulfide ion in Ag2S has the same electron configuration as the noble gas argon (Ar).
A Lewis electron-dot diagram is a representation of the valence electrons in an atom or a compound. The compound that tarnishes silver is silver sulfide (Ag2S). The Lewis electron-dot diagram for Ag2S can be drawn by representing the valence electrons of each element.
The sulfide ion in Ag2S has the same electron configuration as the noble gas argon (Ar). This means that the electron configuration of the sulfide ion is 1s2 2s2 2p6 3s2 3p6.

Because compounds are made of molecules but we need to mention the type of compound formed.
B) generating outcomes based on some model of how they are really produced
C) comparing the outcomes of two different treatment protocols
D) recording the high and low temperature at a particular location every day
Answer: D) recording the high and low temperature at a particular location every day.
Explanation:
A experiment is a process which is conducted or performed to either support, refute or validate the hypothesis. It involves the detail repeatable procedure and the logical analysis of the outcomes of the results. It involves different variables which are compared to obtain the outcome of the experiment. For example the amount of water used everyday responsible for the plant height.
Among the options given, D) recording the high and low temperature at a particular location every day. is the correct option, temperature is a variable in the experiment. The change in the daily temperature of a location can be noted as observation of the experiment. This observation can be used to record the average temperature of the location.
