Identify the following neutral elements by their condensed electron configurations. (Enter the chemical symbol or name of the el

ement.)
(i) [Kr] 5s1 4d10


(ii) [Xe] 6s2 4f14 5d7


(iii) [Ar] 4s2 3d10 4p4


(iv) [Kr] 5s1 4d4


(v) [Xe] 6s1 4f14 5d10


(vi) [Kr] 5s2 4d10 5p4


(b) Based on the electron configurations in part (a), which of the identified elements will have similar properties? Explain. (Enter the chemical symbols of the elements. Separate substances in a list with a comma.)

Elements with similar electron configurations, regardless of which shell each subshell is in, will likely have similar properties.

There are two atoms with the same number of electrons in the outermost d subshell.

Answer: [Kr] 5s1 4d10 silver

[Xe] 6s2 4f14 5d7 Iridium

[Ar] 4s2 3d10 4p4 selenium

[Kr] 5s1 4d4 niobium

[Xe] 6s1 4f14 5d10 gold

[Kr] 5s2 4d10 5p4 tellurium

Explanation:

Selenium and tellurium will have the same properties because they both belong to group 16 in the periodic table.

Silver and gold will have the same properties because they both belong the group 11 in the periodic table.

Elements having the same outermost shell configuration show similar properties since chemical reactions occur by loss or gain of electrons. This loss or gain is determined by the number of electrons occupying the outermost shell. Elements in the same group have the same outermost shell electron configuration and similar properties.

Which of the following observations would indicate that a material is a pure substance?
Ira Lisetskai [31]
<span>The answer to the question is the option C. it cannot be physically broken down into different types of atoms. This means that the material is an element, which is a pure substance. Because an element is a pure substance that is formed by one only type of atoms. For example, gold is an element and all its atoms are of the same type. That is also true for any of the 118 elements of the periodic table. Compounds (other kind of pure substances) can be broken down into molecules (which contain different kind of atoms, but always in the same proportion) and mixtures (non pure substances) have different kind of substances.</span>
