Which neutral atom has the excited- or ground-state electron configuration, [Ar]4s'3d ? Enter the name of the element. [Ar]4s'3d°: Which neutral atom has the excited- or ground-state electron configuration, [Ar]4s'3d!0 ? Enter the name of the element. [Ar]4s'3d!0:

Write the electron configuration for the ground state of Hg2+ (mercury 2+). Use the noble gas shortcut. Since Canvas doesn't support superscripts and the like, type in the electron configuration with a space between each sublevel, and without special formatting. For example, [He]2s2p? would be typed in the answer box as "[He] 2s2 2p2".

Identify the neutral element represented by this excited‑state electron configuration, then write the ground‑state electron configuration for that element. excited state: 1s22s12p03s1

Identify the neutral element represented by this excited‑state electron configuration.   excited state: 1?2 2?2 2?6 3?2 3?0 4?1 Write the full ground‑state electron configuration for that element.

Pls help ASAP. Pls do all asked questions.

Write the ground-state electron configuration for calcium, Ca. You may write either the full or condensed electron configuration. x x. He -, | 8. Write out the ground-state electron configuration for chlorine, CI. You may write either the full or condensed electron configuration. x| x. He 8.

This energy diagram shows the allowed energy levels of an electron in a certain atom. (Note: the SI prefix 'zepto' means 10-21. You can find the meaning of any SI prefix in the ALEKS Data tab.) energy (zJ) 1400 1200 1000 800 600 400 200 0 I B -A Use this diagram to complete the table below. What is the energy of the electron in the ground state? What is the energy of the electron in the first excited state? If the electron makes the transition shown by the red arrow, from A to C, will a photon be absorbed or emitted? Calculate the wavelength of the photon that would be absorbed or emitted. Round your answer to 3 significant digits. 250 ZJ 400 ZJ absorbed emitted nm x10 X S

Which of the following abbreviated electron configuration is correct for the element or ion shown with it? Hint: Consider your exceptions to the orbital filling rules. O Kr: [Ar] 4s2 4p6 4d10 O Zn²+: [Ar]4s²3d8 Se² [Ar]4s¹ 3d¹14p6 O As: [Ar]3d10 4s³ 4p² O Cr³+: [Ar] 3d³

Enter the electron configuration for phosphorus. Express your answer in order of increasing orbital energy as a string without blank space between orbitals. For example, the electron configuration of Li could be entered as 1s^22s^1 or [He]2s^1.
