Question:

What are the answers to these 4 chemistry questions which involve orbitals and electron configurations?

Please answer the four questions with 100% accuracy:Identify the element and write the excited and ground state electron con?guration.1) An element with 13 electrons and its last electron has been excited into the 5p orbital.2) An element with 24 electrons and its last electron has been excited into the 4p orbital.3) An element with 16 neutrons and its last electron has been excited into the 5s orbital.4) An element with 20 neutrons and its last electron has been excited into the 6p orbital.

Answer:

1) AtNo13 is AluminumGround state:[Ne]3s?3p Excited state: [Ne]3s?5p 2) AtNo24 is ChromiumGround state: [Ar]4s?3d? Excited state: [Ar]4s?3d?4p 3) Titanium 48; AtNo22, AtWt 48 Ground state: [Ar]4s?3d? Excited state: [Ar]4s?3d5s 4) Calcium 40; At No 20, AtWt 40 Ground state: [Ar]4s? Excited state: [Ar]4s6p
