What family/group is Sodium (Na) in the periodic table? How about Calcium (Ca)?

If such a compound existed, it would be ionic. Calcium (IV) Chloride.\n\nBut it won't exist, particularly as an ionic compound. You're not going to be able to pull the p electrons from the calcium without a fight and chlorine isn't strong enough (or even fluorine, for that matter). Maybe you can achieve the species in the gas phase ... I don't know.\n\nIf it's covalent, what possible structure could it have? What do the bonding orbitals look like?

Those are the alkaline earth metals, technically referred to as Group 2.  They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra).  Radium has two valence electrons and is in Group 2, but is sometimes left off lists of the alkaline earth metals because it is radioactive.

I'll make it easy for you.All the metals forms positive ions by losing electrons and all non-metals form negative ions by gaining electrons.\nExample:- NaCl  Na+ & Cl-

NaCl - sodium chloride

Sodium chloride , NaCl , is a cubic crystal. Each Na+ is surrounded by 6 Cl- and each Cl- is surrounded by 6 Na+

Zinc is by far the best element. I also like plutonium.  It's just fun to say. "Plutonium."

Na+ is missing an *electron*

Column 1 on the left is alkali metals (not counting hydrogen).\n\nColumn 2 is alkaline earth metals.\n\nColumns 3-12 are transition metals\n\nColumn 13 is the Boron Group\n\nColumn 14 is the Carbon Group\n\nColumn 15 is the pnicogens\n\nColumn 16 is the chalcogens\n\nColumn 17 is the halogens\n\nColumn 18 is the noble gases\n\nThe ones down on the bottom are the rare earth metals... top row is the lanthanide series, bottom row the actinide series

you need a periodic table... just look for the symbol NA... and the atomic number 15, also look for it on the table.. it shud be under the 2-3 letter symbol of the element.

Ionic compounds (like NaCl) for lattice structures.  These lattice structures make up the crystaline arrangement of the compound.\n\nThe lattice of NaCl looks like a cube,\nhttp://zimmer.csufresno.edu/~davidz/Chem3AF97/ChB/IonicBond.html\nhttp://departments.kings.edu/chemlab/chemlab_v2/nacl.html

No. Look at the periodic chart, also called the table of elements. Its even in the dictionary. So is alkaline. Finding that would have been easier than going to Yahoo answers, had you tried.

Calcium is the chemical element in the periodic table that has the symbol Ca and atomic number 20. Calcium is a soft grey alkaline earth metal that is used as a reducing agent in the extraction of thorium, zirconium and uranium. Calcium is also the fifth most abundant element in the Earth's crust. It is essential for living organisms, particularly in cell physiology, and is the most common metal in many animals.\n\nIT MAKES YOUR BONES STRONGER - and prevents osteoporosis

This is an answer I gave a few weeks ago. It helped me to get from failing Chemistry to University....maybe it will help you to understand the periodic table as well.\n\nMy Chemistry teacher taught me a great story which helped me learn the elements, which groups they were in, which periods, how many electrons they had etc and resulted in me going from a grade F to B. Every kid should learn this.\n\nHorrible Hairy Little Begger Boys Catch Newts On Friday Near Naples, Magnificent Albert Sits Planning Some Clever Arrangement Keeping Calm.\n\nOk, looks crazy until you break it down;\n\nH He Li Be B C N O F Ne Na, Mg Al Si P S CL Ar K Ca\n\nThen put it into the table\n\nH\nHe\nLi Be B C N O F Ne\nNa Mg Al Si P S Cl Ar \nK Ca\n\nYou will need to line them up because Yahoo has left align, but the trick is the story. \n\nThe groups 1-8 (across the table) tell you how many electrons are in the outer shell, the periods (down the table) tell you how many shells an element has. etc\n\neg Sodium (Na+, group 1) bonds with Chlorine (Cl- , group 7) because Chlorine has 7 electrons in its outer shell. It needs the one from sodium to become stable.....NaCl (kitchen salt). This is the basis for other compund formation....ie water H2O and so on.\n\nLearn the story above and everything will fall into place.\n\nHope this helps!
