Answer to Problem 23P

Fill in accordance with the periodic table: 1s22s22p63s23p63d74s2

Explanation of Solution

Given info: Atomic number, Z=27

Formula used:

Arrangement or structure of electrons in the energy levels in the region of an atomic nucleus is known as Electronic structure or electronic configuration. In electronic configuration, spdf demotes to the shape of any orbital. The spdf notation employs numbers to designate principal shell and also, letters (s,p,d,f) to categorize a sub shell. In spdf notation, subscript indicates the numeral of electrons in a designated sub shell.

Calculation:

If l is an angular quantum number of sub shell then max electrons it can hold: N=2(2l+1)

Thus, in spdf maximum electrons are 2,6,10,14  respectively.

Now, start with hydrogen and fill the levels as indicated in the periodic table:

  1s22s22p63s23p63d74s2

Understand that 4s2 level is filled before the 3d level is started.

(b)

To determine

The full electron configuration in the ground state for elements with Z equal to 36

Answer to Problem 23P

Fill in accordance with the periodic table: 1s22s22p63s23p63d104s24p6

Explanation of Solution

Given info: Atomic number, Z=36

Formula used:

Arrangement or structure of electrons in the energy levels in the region of an atomic nucleus is known as Electronic structure or electronic configuration. In electronic configuration, spdf demotes to the shape of any orbital. The spdf notation employs numbers to designate principal shell and also, letters (s,p,d,f) to categorize a sub shell. In spdf notation, subscript indicates the numeral of electrons in a designated sub shell.

Calculation:

If l is an angular quantum number of sub shell then max electrons it can hold: N=2(2l+1)

In, spdf maximum electrons are 2,6,10,14  respectively.

For Z=36 , electronic configuration is

  1s22s22p63s23p63d104s24p6

(c)

To determine

The full electron configuration in the ground state for elements with Z equal to 38

Answer to Problem 23P

Fill in accordance with the periodic table: 1s22s22p63s23p63d104s24p65s2

Explanation of Solution

Given info: Atomic number, Z=38

Formula used:

Arrangement or structure of electrons in the energy levels in the region of an atomic nucleus is known as Electronic structure or electronic configuration. In electronic configuration, spdf demotes to the shape of any orbital. The spdf notation employs numbers to designate principal shell and also, letters (s,p,d,f) to categorize a sub shell. In spdf notation, subscript indicates the numeral of electrons in a designated sub shell.

Calculation:

If l is an angular quantum number of sub shell then max electrons it can hold: N=2(2l+1)

Thus, in spdf maximum electrons are 2,6,10,14  respectively.

For Z=38 ,

  1s22s22p63s23p63d104s24p65s2

Understand that 5s2 level is filled before the 4d level is started.
