Metals are sodium, calcium and aluminium.
The pair that is different from the others is B-Al. This is because B (Boron) and Al (Aluminum) are both non-metals or metalloids, whereas Li (Lithium), Mg (Magnesium), Na (Sodium), K (Potassium), and Ca (Calcium) are all metals. The other pairs consist of metals only, while B and Al represent a different category of elements.
The chemical formula of scapolite is Na4Ca4Al6Si12O36(Cl,CO3). There are 6 different elements in this formula: sodium (Na), calcium (Ca), aluminum (Al), silicon (Si), oxygen (O), and chlorine (Cl).
(Na,Ca)8[(S,Cl,SO4,OH)2|(Al6Si6O24)].
x Al(Al,Si)3O8, where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K).
Na, sodium, should have the lowest first ionization energy of those four elements.
Metals as Al, Na, Fe, Ca, Mg, etc.
The composition is variable: bicarbonates and hydroxides of some metals as Na, K, Ca, Mg, Al.
The order from highest to lowest ionization energy is Cl > Al > Si > Na > S. This is because ionization energy generally increases from left to right and from bottom to top in the periodic table.
Examples: - Sr, Li as carbonates - Na, Cs, K, Rb as nitrates - Ca, Ba, Cu as chlorides - powdered metals as Ti, Al, Be, Mg, Fe etc.
Fluorine has the most electronegative element, Cl and Br
Examples are Na+, K+, Mg+, Ca+, Cl-.
The chemical formula of scapolite is Na4Ca4Al6Si12O36(Cl,CO3). There are 6 different elements in this formula: sodium (Na), calcium (Ca), aluminum (Al), silicon (Si), oxygen (O), and chlorine (Cl).
H, He, Li, Be, B., C, O, N, F, Ne, Na, Ma, Al, Si, P, S, Cl, Ar, K, Ca.
Na and K are both metals and do not react Na and Cl are metal and non metal respectively and will form ionic compound, NaCl or table salt or sodium chloride Mg and Li are both metals and do not react S and Cl are both non metals and will give covalent compounds
Ionic bond is when a non-metal takes the metals valance electrons so both atoms can be balanced. Take NaCl for example. Na has one valance electron and Cl only needs one to get eight. So Cl takes Na's one valance electron...:Cl: Na. See the empty spot for Cl, that where Na's valance electron will go.'
