the formation of cations by using electron dot structures are :

a) Al

.

Al .    losing the three valence electrons makes the Al³⁺

.

b) Sr :  

  Sr :  losing the two valence electrons makes Sr²⁺

c) Ba

: Ba , losing the two valence electrons makes it Ba²⁺

A Lewis electron dot diagram is a representation of the valence electrons of an atom that employments specks around the image of the element. The number of dots equals the number of valence electrons within the molecule. These dots are arranged to the right and left and over and underneath the symbol, with no more than two dots on a side. Cations are the positive ions shaped by the loss of one or more electrons. The foremost commonly shaped cations of the representative elements are those that include the loss of all of the valence electrons.

What separates the charges in a cell?
erica [24]

Answer:

Atoms start out with the same number of negative charges (electrons), and positive charges (protons). ... Conversely, adding electrons to an atom would result in a negative ion. If you do this enough times, you can make an object positive or negative. Friction is one of the ways to separate charge.

Balance the following redox equation, using half-reactions. Assume that the reaction occurs in an aqueous solution.
anastassius [24]
First determine the formal oxidation numbers: 
N changes from +2 to +5 going from NO to (NO3)- O remains -2 the whole time Cr changes from +6 to +3 
Now write the half reactions, balance the oxygens with the required number of waters and then balance the hydrogens with the required number of protons: 
Oxidation half reaction: 
NO(aq) + 2 H2O(l) ---> (NO3)-(aq) + 4 H+(aq) + 3 e- 
Reduction half reaction: 
(Cr2O7)2-(aq) + 14 H+(aq) + 6 e- ---> 2 Cr3+(aq) + 7 H2O(l) 
Now balance the number of electrons on both sides and add them together: 
2 NO(aq) + 4 H2O(l) ---> 2 (NO3)-(aq) + 8 H+(aq) + 6 e- (Cr2O7)2-(aq) + 14 H+(aq) + 6 e- ---> 2 Cr3+(aq) + 7 H2O(l) --------------------------------------... 2 NO(aq) + (Cr2O7)2-(aq) + 6 H+(aq) ---> 2 (NO3)-(aq) + 2 Cr3+(aq) + 3 H2O(l) 
Notice that the charge is the same in both sides, which is an indication that the redox equation has been balanced correctly: 
-2 + 6 = -2 + 2(+3) +4 = +4
