Question

1. __ sublevel. rows 6 and 7 contain elements that are placed at the bottom of the periodic table. these are known as the 14. and 15. section. these elements have valence electrons filling the 16. sublevel. more specifically, the elements from period 6 are called 17. and the ones from period 7 are called 18. . certain groups of elements in the periodic table also have specific names. for instance, elements in column 1 are also called 19. . the elements in column 2 are called 20. . the elements in column 17 are called 21. . the elements in column 18 are called 22. . the elements of column 1 and 2 have valence electrons filling the 23. sublevel. the elements in column 13–18 have valence electrons filling the 24. __ sublevel.

the elements on the right side of the periodic table are classified as 25. __, while elements on the left side of the table are classified as 26. . a few elements found in between have characteristics of both groups and are referred to as 27. __.

Explanation:

To solve this fill - in - the - blank problem about the periodic table, we use our knowledge of the structure and classification of elements in the periodic table:

Question 13

The sublevel related to the elements in rows 6 and 7 (the inner transition metals) is the $f$ sublevel. So the answer is $f$.

Question 14

The elements at the bottom of the periodic table (rows 6 and 7) are divided into two sections. The first section (for period 6) is known as the Lanthanide section. So the answer is Lanthanide.

Question 15

The second section (for period 7) of the elements at the bottom of the periodic table is known as the Actinide section. So the answer is Actinide.

Question 16

The inner transition metals (Lanthanides and Actinides) have valence electrons filling the $f$ sublevel. So the answer is $f$.

Question 17

The elements from period 6 in the inner transition metal section (bottom of the periodic table) are called Lanthanides. So the answer is Lanthanides.

Question 18

The elements from period 7 in the inner transition metal section (bottom of the periodic table) are called Actinides. So the answer is Actinides.

Question 19

The elements in column 1 of the periodic table are called Alkali Metals. So the answer is Alkali Metals.

Question 20

The elements in column 2 of the periodic table are called Alkaline Earth Metals. So the answer is Alkaline Earth Metals.

Question 21

The elements in column 17 of the periodic table are called Halogens. So the answer is Halogens.

Question 22

The elements in column 18 of the periodic table are called Noble Gases. So the answer is Noble Gases.

Question 23

The elements in column 1 and 2 (the s - block elements) have valence electrons filling the $s$ sublevel. So the answer is $s$.

Question 24

The elements in column 13 - 18 (the p - block elements) have valence electrons filling the $p$ sublevel. So the answer is $p$.

Question 25

The elements on the right side of the periodic table (excluding the noble gases in some classifications, but generally the non - metals and some metalloids) are classified as Non - metals.

Question 26

The elements on the left side of the periodic table (the alkali metals, alkaline earth metals, and transition metals) are classified as Metals.

Question 27

The elements that have characteristics of both metals and non - metals are called Metalloids.
