Which of the following pair is chemically similar?
F and Cl are chemically similar Hence, we can conclude that elements in the same group of the periodic table have similar properties because they have same number of valence electrons. Only Florine (F) and chlorine belong to same group and thus are chemically similar.
Which two elements have the most similar physical and chemical 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.
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).
Which of the following atomic number of elements have similar chemical properties?
The elements with the atomic number 3 and 11 have the same properties because both elements have same valence shell configuration, i.e., ns1.
Why sodium and potassium have similar chemical 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.
What two elements have 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.
Which two of the following elements would you expect to show the greatest similarity in chemical and physical properties explain b Ca F he Mg P?
Which two of the following elements would you expect to show the greatest similarity in chemical and physical properties: B, Ca, F, He, Mg, P? Elements that are in the same group of the periodic table are most likely to exhibit similar chemical and physical properties.
Which pair of atoms would be expected to have similar chemical properties?
Chemistry is largely the result of interactions between the valence electrons of different atoms. Thus, atoms that have the same valence shell electron configuration will have similar chemistry.
Which of the following will have same chemical properties?
Isotopes have same electronic configuration as they have same atomic number. Thus they have similar chemical properties. Hence the correct answer is option A. Isotopes.
What are 3 elements that have similar properties?
The elements in the first column of the Periodic Table (other than hydrogen) are known as Group 1A metals, or alkali metals. When you compare the chemical properties of these elements (lithium, sodium, potassium, rubidium, cesium, and francium), what you'll notice is that they are all remarkably similar.
Why lithium and sodium has similar chemical properties?
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).
What are similar chemical properties?
Elements with the same number of valence electrons have similar chemical properties.
What elements exhibit 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 two elements have similar chemical properties explain?
Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. Elements in the same column of the Periodic Table have similar chemical properties.
Which two elements will have similar physical and chemical 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.
Which one of the following pair of elements has similar properties?
The elements 13 (Aluminium) and 31 (Galium) both belong to same group i.e., III A. Therefore, both elements have similar electronic configuration of the outermost shell and hence have similar properties.
Which pair of elements has the similar chemical properties Z means atomic number?
The elements with the atomic number 3 and 11 have the same properties because both elements have same valence shell configuration, i.e., ns1.
Which of the following have similar chemical properties?
Isotopes have same electronic configuration as they have same atomic number. Thus they have similar chemical properties. Hence the correct answer is option A. Isotopes.
Does sodium and magnesium have similar chemical properties?
Both Sodium and Magnesium have third electron shell 3s as their outermost valence electrons, therefore they are in the same period. This period corresponds to the accumulation of electrons in the third (n = 3) shell, especially its 3s and 3p subshells, in a quantum mechanical explanation of atomic structure.
Why do elements of the same group have similar chemical properties?
Elements within the same group have the same number of electrons in their valence (outermost) shells, and they have similar electron configurations. They exhibit similar chemical properties.
Where are elements with similar chemical properties found on the periodic table?
groups The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Which of the following pairs will have same chemical property?
Two elements that have properties similar to those of the element sodium and Potassium (K) and Lithium (Li) because they are in the same group. … The elements of potassium and sodium have similar chemical properties because they have the same number of valence electrons and form +1 ions.
Which pair of elements with given atomic numbers will have the same chemical properties?
The elements with the atomic number 3 and 11 have the same properties because both elements have same valence shell configuration, i.e., ns1.
Why the elements of the same group have similar chemical properties?
The elements of same group have similar chemical properties because they have same number of valence electrons.
Why the elements belonging to the same group 2 have similar chemical properties?
So, we can say that elements in a group have the same physical and chemical properties because their atoms have the same number of valence electrons or same valence shell electronic configuration.
What are two elements that have similar chemical properties?
The elements in the first column of the Periodic Table (other than hydrogen) are known as Group 1A metals, or alkali metals. When you compare the chemical properties of these elements (lithium, sodium, potassium, rubidium, cesium, and francium), what you'll notice is that they are all remarkably similar.
