(Na,Ca)8[(S,Cl,SO4,OH)2|(Al6Si6O24)].
What element will most easily lose an electron from Al Cl NA Zn?
Na, sodium, should have the lowest first ionization energy of those four elements.
What is feldspar's chemical formula?
x Al(Al,Si)3O8, where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K).
What bonds is the strongest Na-I or Na-Cl or K-I or K-Cl?
In neurons, ________ ions are at higher concentration inside the cell and ________ ions are at higher concentration in the extracellular fluid. A) Cl; organically bound B) Cl; K C) K; Na D) Cl; Na E) Na; K
What kind of metals are there most of in the periodic table?
Metals as Al, Na, Fe, Ca, Mg, etc.
What is S Si Na Al and Cl in order from highest ionization energy to lowest?
The order is: Cl,S, Si, Al, Na.
Which chemicals can be found in indigestation tablets?
The composition is variable: bicarbonates and hydroxides of some metals as Na, K, Ca, Mg, Al.
Which of the two following two elements will likely form an ionic bond na and k na and cl mg and li s and cl?
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
What element reacts with H2O to produce H2?
All metals more reactive than Zn: Al, Mg, Na, Ca, Ba, K, Li
Which Metals are used to make the colors in fireworks?
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.
What are three examples of dissolved ions in the ocean?
Examples are Na+, K+, Mg+, Ca+, Cl-.
What is the reaction of Na Cl -- Na-Cl?
NaCl-----------------Na+ + Cl-is a dissociation reaction.
Of the metals Pb Hg Na and Ca which is the most difficult to oxidize?
Hg
First 20 elements in the periodic table with their symbols?
H, He, Li, Be, B., C, O, N, F, Ne, Na, Ma, Al, Si, P, S, Cl, Ar, K, Ca.
What is ionic bonding structure?
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.'
What has the smallest atomic radius Na Mg Cl Al?
chlorine. across a period the size decreases
