Why Mg is harder than Na?
Mg. Mg has 2 valence electrons while Na only has 1 valence electron. Mg+2 also has a smaller ionic radius than Na+. Metallic bonds are stronger when metals have more valence electrons and smaller ion size. The metallic bond will be stronger for Mg. Thus, Mg will have the higher melting point.
What element would have properties most like ca?
Mg
Why na and mg have same number of electrons but removal of electron from mg requires more energy?
na is more electropositive. it is so as electropositivity decreases from left to right across a group
Are lithium and potassium similar properties?
Yes, they have similar chemical properties.
Which element has chemical properties most similar to those of the element calcium?
atoms in the same group are similar. calcium is in group 2, so it's similar to Be, Mg, Sr, Ba and Ra. Most similar would be Mg or Sr, which are right above and below. all group 2 atoms share a similar electron configuration
Are the properties of sodium Na more like the properties of lithium or magnesium?
Na is chemically more like Li than Mg, only physically (measurements, mass) it looks more like Mg
Are the properties of sodium Na more like the properties of lithium or magnesium mg?
Na is chemically more like Li than Mg, only physically (measurements, mass) it looks more like Mg
How are the properties of sodium Na similar to or different from the properties of lithium Li or magnesium Mg?
The key difference between sodium and sodium chloride is that sodium is a chemical element whereas sodium chloride is a compound containing both sodium and chlorine chemical elements.
What is most similar to calcium K Sc Mg Na?
Calcium (Ca) and magnesium (Mg) are similar as both of them have two valence electrons.
What element has the same chemical properties as neon?
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) .
The elements of the periodic table have similar properties in?
The answer is SOMETIMES. Look in the 3rd period of the periodic table. Sodium (Na) and Magnesium (Mg) both fall into the "metal" category, and therefore share the same properties. Such as:Conducting heat and electricityBeing malleable and ductileBeing solid at room temperature.HOWEVER, when comparing Sodium (Na) to Argon (Ar), which are both in the same period, you are then comparing the properties of a METAL (Sodium) to a NONMETAL (Argon). Metals and nonmetals could not be more different = different properties.Sorry for the long answer.
What groups of metals on the periodic table would have the most similar properties?
Group-1 and 2 have metallic properties. They possess same properties.
S na cl mg witch one is largest?
Na :)
