Which elements have more similar properties?
Two different elements are likely to have similar chemical properties when they have the same number of valence electrons. Elements with the same number of valence electrons are found in the same column of the Periodic Table. Elements with the same valence shell are found in the same row on the Periodic Table.
What pairs of elements are most similar?
UPLOAD PHOTO AND GET THE ANSWER NOW! Solution : Zr and Hf are chemically most similar, they have same atomic size. Hence, they are known as twins of the periodic table.
Which elements have the most similar properties K and Na?
So, the elements with similar properties to sodium (Na) are all of those elements in the same Group. The ones "most" similar would be the ones closest in mass as well. Those would be Lithium (Li) and Potassium (K).
Which elements are most similar?
Which elements have the most similar chemical properties? Valence electrons
- boron and carbon.
- oxygen and sulfur.
- aluminum and bromine.
- argon and silicon.

Which list represents elements that share the most similar chemical properties?
Answer and Explanation: The elements that have the most similar chemical properties are those in the same group, or column of the periodic table.
Which two elements will display the most similar chemical properties?
Li lithium and K potassium both belong to first group (alkali metals) and thus have similar chemical properties.

Why do elements have similar properties?
Elements in the group have similar chemical properties. This is because their atoms have the same number of electron in the highest occupied energy level. Was this answer helpful?
Why do Group 7 elements have similar properties?
The halogens are found in group 7 of the Periodic Table and are one electron away from a full outer shell of electrons. The halogens include the elements chlorine, bromine and iodine which all behave in similar ways due to similarities in their electron configurations.
Which elements are more similar in chemical and physical properties?
Sodium and potassium share similar physical and chemical properties because they are in the same family or group called Alkali metals. Both will have the same valence electrons and they are both very reactive.
Why do group 8 elements have similar chemical properties?
Elements in the group have similar chemical properties. This is because their atoms have the same number of electron in the highest occupied energy level.
Why do group 1 elements have similar reactions?
The elements in the first column of the Periodic Table (lithium, sodium, potassium and so on) all have one electron in their outer electron shell. This means that they share similar properties and behave similarly in chemical reactions.
Why all the elements of a group have similar chemical properties?
- According to Modern periodic law, the physical and chemical properties of an element depend on the number of electrons in the valence shell of the atom.
- In a group, all the elements have the same number of valence electrons.
- So, we can say that elements in the same groups have similar chemical properties.
Why do all elements of the same group have similar properties?
The chemical properties of an atom are largely determined by its valence electrons.In a given group, the number of valence electrons are same,hence they have similar properties.
What are the similarities between group 1 and group 2 elements?
Both the groups contain metals. group 1 is for alkali metals and group 2 is for alkaline earth metals. group 1 metals are monovalent while group 2 metals are divalent.
Why do elements in a group have similar properties?
The chemical properties of an atom are largely determined by its valence electrons.In a given group, the number of valence electrons are same,hence they have similar properties.
What elements have similar physical and chemical properties?
The answer is b. Elements in the same group have the same number of valence electrons and so interact with other elements in a similar way. They display similar physical and chemical properties. For example, the halogens (F, Cl, Br, I) all react similarly.
Which pair of atoms have similar properties?
For example, pairs lithium (Li) and magnesium (Mg), beryllium (Be) and aluminium (Al), boron (B) and silicon (Si), etc are exhibiting similar properties. Boron and Silicon are both semiconductors. Thus Magnesium and Lithium have similar properties.
Why elements in a same group have similar properties give two examples?
i) Among the given elements, 19K has one electron in the outermost shell. ii) Elements 4Be and 20Ca both have two electrons each in their outermost shells. Therefore, both these elements belong to the same group. Electronic configuration of element X is 2, 8, 7.
Which two elements are most likely in the same group and why?
Aluminum, boron, and gallium are likely together in one group because they have the same number of valence electrons, and carbon and germanium are likely together in another group because they have the same number of valence electrons.
What is the similarity of each element in a group?
In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts. This similarity in both the composition and structure of their atomic valence shells implies a corresponding similarity in both their chemical and physical properties.
Why do metals have similar properties?
A metal. Elements within the same group/family of the periodic table have what? Similar properties because they have the same number of valence electrons. Electrons in the outer level of an atom available to be lost, gained, or shared.
Which pair of elements will share the greatest similarities in physical and chemical properties?
The pair of elements that would exhibit the greatest similarity in their properties is C. Ca, Sr.
Why elements in the same family have similar properties?
Because the members of each group in the main group elements has the same number of valence electrons, there are similar properties and similar trends in chemical reactions found in the group.
Which pair of elements is most likely to have similar properties and reactivity?
1 Answer. Boron and aluminium are in the same group (iii), thereby will show similar chemical behaviour during chemical reactions.
Do elements in the same group have similar properties?
The elements in the same group have similar chemical properties because they have the same valence shell electron configuration. The elements in a row show a gradual change in chemical properties because their valence shell electron configuration changes gradually along the row.
Why do all the elements of same group have similar properties?
The chemical properties of an atom are largely determined by its valence electrons.In a given group, the number of valence electrons are same,hence they have similar properties.
Which of the following elements would you expect to have properties most similar to those of bromine?
1 Expert Answer. Fluorine (not florine) would have properties very similar to bromine. They are both halogens (group XVIII).
