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. So, the correct answer is “Option A”.
Which elements would exhibit similar chemical properties?
Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.
Which pair of elements will most likely exhibit similar chemical properties?
Elements that are in the same group of the periodic table are most likely to exhibit similar chemical and physical properties. We therefore expect that Ca and Mg should be most alike because they are in the same group (group 2A, the alkaline earth metals).
What are 3 elements that have similar properties?
Magnesium, strontium, and barium belong to group 2A of the periodic table. These have two valence electrons in their outermost shell. So these three elements have similar chemical properties.
Do I and CA have similar properties?
Calcium and potassium are both metals. ... Calcium and potassium have a different number of valence electrons. Correct! Elements within in the same group/family have similar chemical properties due to the fact that they have the same number of valence electrons .
What are 2 elements that have similar properties?
- Finding what elements have the most similar chemical properties is easy. ...
- Let’s try an example.
- Which two elements have the most similar chemical properties?
- (1) beryllium and magnesium.
- (2) hydrogen and helium.
Why are the chemical properties of Na K and Rb similar?
The reason for the similarity in a group is due the outer shell with valence electrons . So in Group 1A, which contains H, Li, Na, K, Rb, Cs, Fr, they have one valence electron or some may have similar physical properties as well ex.
Which two elements will have similar physical and chemical properties?
Explain your answer. 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 elements have the same properties?
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. So what does that mean about their valence electrons?
What has 12 protons and 25 neutrons?
#12 – Magnesium – Mg . It is the eighth most common element in the earth’s crust, but is the most commercially used element.
What element is in Group 14 and Period 3?
Silicon (symbol Si) is a group 14 metalloid.
Which has chemical properties most similar to CA?
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium .
Why do NA and CA have similar properties?
Explanation: Chemical “properties” are based on their electron structure, and it is how the Periodic Table of the Elements is constructed. ... 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.
What elements are the most similar?
What element has the most 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) .
Are Group 2 oxides basic?
Similarly to Group 1 oxides, most group 2 oxides and hydroxides are only slightly soluble in water and form basic , or alkaline solutions.
