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.
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
Why Na Mg are bridge elements?
NA and MG are bridge elements because some of the second period elements show a diagonal relationship with the third period elements. Other examples would be LI and MG.
What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
Which elements are in this chemical reaction Na s plus MgF2 s NaF s plus Mg s?
The elements involved in this reaction are sodium (Na) and magnesium (Mg). The reaction occurs between solid sodium (Na) and solid magnesium fluoride (MgF2) to form solid sodium fluoride (NaF) and solid magnesium (Mg).
What element is the largest Mg S Na CI?
Sodium (Na) is the largest element among Mg (magnesium), S (sulfur), Na (sodium), and Cl (chlorine) when comparing their atomic radii. Sodium has the largest atomic radius because it is located in the third period of the periodic table, whereas magnesium is smaller due to being in the second period.
S na cl mg witch one is largest?
Magnesium (Mg) is the largest atom among sulfur (S), sodium (Na), chlorine (Cl), and magnesium (Mg). This is because the size of an atom increases as you move down a group in the periodic table. Magnesium is located below the other elements in the periodic table, making it the largest atom among these options.
Choose the element that is largest Li Na Rb K?
Rb (Rubidium) is the largest element among Li, Na, Rb, and K as you move down the same group or in the same period from left to right on the periodic table.
Which if these are a molecule Ca Mg Na H2O?
H2O. Notice the presence of two elements, H and O. Each of the other three is an element.
What is the chemical symbol CI?
There is no chemical symbol CI. If you meant Cl then it is Chlorine.
What element has the element Na?
The element Sodium has the chemical symbol Na. Na is from the Latin Natrium.
Which element is the largest K Rb Na Li?
Rb (rubidium) is the largest element among K (potassium), Rb (rubidium), Na (sodium), and Li (lithium). This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells.
Does Na-CI move into the sac when put in solution?
No
Is Na a compound or and element?
Na is an element. It is Sodium.
Arrange the following ions in increasing order of size Be Cl s na mg br?
From LArgest to smallest it is Br, Mg, Na, Cl, Be.... This is because of ionization the concept is realitivly simple as you go to the right of the peroidic table they do not want to loose there electrons and the attraction of the electrons to the nucleus is greater therefore making the atoms smaller as you go to the right.
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) .
Is na an atom or an element?
"Na" is the symbol of an atom of the element sodium.
