Part 1)

Cu - [Ar] 3d¹⁰4s¹ atomic number: 29

O - [He] 2s2 2p 4 atomic number:8

La - [Xe] 5d¹ 6s² atomic number:57

Y - [Kr] 4d¹5s² atomic number:39

Ba - [Xe] 6s² atomic number:56

Tl - [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p¹ atomic number:81

Bi - [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p³ atomic number:83

Part 2)

You are able to this by consulting the periodic table and following this steps:

-Find your atom's atomic number;

-Determine the charge of the atom (these were all uncharged)

-Memorize the order of orbitals (s, d, p, d ... and how many electrons they can fit)

- Fill in the orbitals according to the number of electrons in the atom

- for long electron configurations, abbreviate with the noble gases
