lectron configuration of a neutral atom is 1s22s22p63s23p2.
a) Draw the orbital diagram.
b) Write a complete set of quantum numbers for each of the electrons.
c) Name the element.
These are difficult to "draw" on this forum. If you will discuss what you don't understand perhaps I can help. By the way, it helps when writing electron configuration if you leave a space like this
1s2 2s2 2p6 3s2 3p2
how do you do 9*9 to the 69
a) To draw the orbital diagram, we represent each electron as an arrow pointing up or down. The 1s orbital can hold a maximum of 2 electrons, the 2s and 2p orbitals can each hold a maximum of 2 electrons, and the 3s and 3p orbitals can each hold a maximum of 2 electrons.
In this case, the electron configuration is: 1s^2 2s^2 2p^6 3s^2 3p^2
The orbital diagram can be represented as follows:
1s: ↑↓
2s: ↑↓
2p: ↑↓ ↑↓ ↑
3s: ↑↓
3p: ↑↓ ↑
b) To determine the quantum numbers for each electron, we need to understand the four quantum numbers: n (principal quantum number), l (azimuthal quantum number), ml (magnetic quantum number), and ms (spin quantum number).
The first electron (1s^2) has the following quantum numbers:
n = 1, l = 0, ml = 0, ms = +1/2 (up arrow)
The second electron (1s^2) also has the same set of quantum numbers:
n = 1, l = 0, ml = 0, ms = -1/2 (down arrow)
The third electron (2s^2) has:
n = 2, l = 0, ml = 0, ms = +1/2 (up arrow)
The fourth electron (2s^2) has the same set of quantum numbers:
n = 2, l = 0, ml = 0, ms = -1/2 (down arrow)
The fifth electron (2p^6) has:
n = 2, l = 1, ml = -1, ms = +1/2 (up arrow)
The sixth electron (2p^6) has:
n = 2, l = 1, ml = 0, ms = +1/2 (up arrow)
For the third, fourth, fifth, and sixth electrons, the ms = -1/2 (down arrow) for each.
c) To determine the name of the element, we need to look at the electron configuration and identify the atomic number. In this case, the electron configuration corresponds to 16 electrons, so the element with this configuration is sulfur (atomic number 16).
