Sort these elements into pairs that would most likely exhibit similar chemical properties. it doesn’t matter which pair goes in which

Explanation:It is known that neutral elements with same number of valence electrons will have same chemical properties. Therefore, elements of same group show similar chemical properties.Thus, we can see that P and As belongs to group 15. So, they will exhibit similar chemical properties.Both Ca and Ba belongs to group 2, hence they will exhibit similar chemical properties. Whereas both He and Ar belongs to group 18 and they will exhibit similar chemical properties.... Show More

The pairs of elements with similar chemical properties are as follows:  Further Explanation:The unique features of varioussubstances that make them different from the other substances are called properties.Classification of properties:Physical properties:While measuring such properties, chemical composition of substances is kept unaltered. These are used for observation and explanation of matter. Density, color, texture, polarity and solubility are some of the examples of physical properties.Chemical properties:These are the characteristics of substances that can be observed during its chemical reaction. Such properties are not predicted by mere observation or by physical appearances Heat of combustion, enthalpy of combustion, toxicity, flammability are some examples of chemical properties.The chemical properties of different elements are dependent on the number of valenceelectrons present in the element. Elements with same number of valence electrons show many similarities in their chemical properties.Atomic number of P is 15 and it has an electronic configuration of   . It has five valence electrons in it.Atomic number of As is 33 and it has an electronic configuration of . It has five valence electrons in it.Since P and As have five valence electrons in each, these belong to group 15of periodic table and have similar chemical properties.Atomic number of Ar is 18 and it has an electronic configuration of . It has eight valence electrons in it. This implies its valence shell is completely filled and it belongs to noble gas family of periodic table.Atomic number of He is 2 and it has an electronic configuration of  . It has two valence electrons in it.This implies its valence shell is completely filled and it belongs to noble gas family of periodic table.Since Ar and He have fulfilled electronic configurations, these belong to group 8 of periodic table and have similar chemical properties.Atomic number of Ba is 56 and it has an electronic configuration of . It has two valence electrons in it.Atomic number of Ca is 20 and it has an electronic configuration of . It has two valence electrons in it.Since Ba and Ca have two valence electrons in each, these belong to group 2 of periodic table and have similar chemical properties.Learn more: Which of these is an extensive property?

Explanation:A property that leads to changes in chemical composition of a substance is known as chemical property. So, when we move down a group in periodic table then chemical properties of the elements remain the same.This is because elements of the same group tend to have same number of valence electrons. Therefore, they have similar reactivity which leads to change in their chemical composition upon reaction with another substance.For example, lithium (Li) and potassium (K) are both group 1 elements. And, phosphorous (P) and arsenic (As) are both group 15 elements.Thus, we can conclude that pair of Li and K will show similar chemical properties. Also, pair of P and As will show similar chemical properties.... Show More

Pair 1 : Na & Rb Pair 2 : O & SePair 3 :  Ne & KrExplanation:Pair  1 are Group 1 elements in the periodic table. They are electro-positive elements that exhibit metallic properties.Pair 2 are Group 6 elements in the periodic table. They are electro-negative elements that exhibit non-metallic properties.Pair 3 are Group 8 or Group 0 elements in the periodic table. They are mainly inert gases.... Show More

Pair 1 : ( F , Br ) Pair 2 : ( Li , K ) Pair 3 : ( P , As )Step-by-step explanation:Following the groups (column number ) in the periodic table (since elements that belong to the same group exhibit similar properties ) we can build the following pairs:Pair 1 : ( F , Br ) → Since both belong to the Halogens group  ( Group number 17) Pair 2 : ( Li , K ) → Since both belong to the Alkali metals group  ( Group number 1) Pair 3 : ( P , As ) → Since both belong to the Pnictogens group ( Group number 15)...

The following pairs of elements would most likely exhibit similar properties:Tellurium (Te) and Sulfur (S)Potassium (K) and Lithium (Li)Neon (Ne) and Krypton (Kr)Further ExplanationThe chemical properties and behavior of elements are determined by the their valence electrons. Elements with the same number of valence electrons will exhibit similar chemical properties. The number of valence electrons can be determined easily from the periodic table. In the periodic table the elements are arranged in columns and rows. Columns are called the groups and the rows are the periods. From left to right, each group is numbered from 1 to 18. The group number gives information about number of valence electrons of the element:Group 1 - 1 valence electronGroup 2 - 2 valence electronsGroup 13 - 3 valence electronsGroup 14 - 4 valence electronsGroup 15 - 5 valence electronsGroup 16 - 6 valence electronsGroup 17 - 7 valence electronsGroup 18 - 8 valence electronsElements that belong to the same group have similar chemical properties.Potassium and Lithium are both Group 1 element and have one valence electron. They are both very reactive with water. They form an alkaline solution with water.Neon and Krypton are both Group 18 or Noble Gases. Both elements have filled valence shells with eight electrons and are very stable and quite unreactive. LEARN MOREPeriodic Trends Periodic Table Keywords: chemical properties, groups,... Show More

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.the first pair: ne (neon) and kr (krypton), are noble gases found in group 8the second pair: li (lithium) and k (potassium), found in group 1the third pair: s (sulfur) and te (tellurium), found in group 6...
