Group 13 of the Periodic Table. They are all metals with low melting points and are commonly used in various industries, including construction and transportation. They have similar chemical properties, such as forming +3 cations.
Sodium (Na) and Magnesium (Mg) are two elements in the same period (period 3).
(Ca,Na)2-3(Mg,Fe,Al)5Si8022(OH)2 The general formula for all amphiboles is Si8O22(OH)2
na is more electropositive. it is so as electropositivity decreases from left to right across a group
crustal Rocks that consists of Ca,Al,Si, Na, K, Mg, Fe and O.
Sodium (Na), Aluminum (Al), and Cobalt (Co) are elements that can exhibit more than one valence state. Sodium can exhibit +1 and +2 states, Aluminum can exhibit +3 and +2 states, and Cobalt can exhibit +2 and +3 states. Magnesium (Mg) typically exhibits a +2 valence state.
Sodium (Na) and Magnesium (Mg) are two elements in the same period (period 3).
B-Al is different from the other pairs because it consists of elements from different groups in the periodic table. Li-Mg, Na-K, and Ca-Mg are pairs of elements from the same group which exhibit similar chemical characteristics.
Na (sodium) (2,8,1) if Na lose the outermost electron,it will be Na+ (2,8) like Ne (neon) (2,8) and Mg (magnesium) (2,8,2) if Mg lose the outer most electron, it will be Mg+2 (2,8) like Ne (2,8) and Al (aluminium) (2,8,3) if Al lose the outermost electron,it will be Al+3 (2,8) like Ne (2,8) .
(Ca,Na)2-3(Mg,Fe,Al)5Si8022(OH)2 The general formula for all amphiboles is Si8O22(OH)2
Metals as Al, Na, Fe, Ca, Mg, etc.

crustal Rocks that consists of Ca,Al,Si, Na, K, Mg, Fe and O.
Sodium (Na), Aluminum (Al), and Cobalt (Co) are elements that can exhibit more than one valence state. Sodium can exhibit +1 and +2 states, Aluminum can exhibit +3 and +2 states, and Cobalt can exhibit +2 and +3 states. Magnesium (Mg) typically exhibits a +2 valence state.
All of these elements belong to same period. The period number is 3.
The composition is variable: bicarbonates and hydroxides of some metals as Na, K, Ca, Mg, Al.
