By increasing Atomic number
Answer:
Nickel (Ni) is most likely to form more than one kind of positively charged ion as it is a transition metal and all of the ther metals have a fixed ion charge.
Na becomes Na+
Ba becomes Ba +2
Mg becomes Mg+2

The two stable isotopes of lithium are Lithium 6 with three neutrons and lithium 7 with four neutrons. Lithium 7 is the predominant isotope, about 92.5%.
Answer:
Magnet with a positive and a negative pole
Explanation:
A great analogy to demonstrate what a polar molecule looks like is to imagine a magnet. A magnet has one positively charged end and one negatively charged end, two poles, that is.
Imagine that we have a magnet of a shape of a prism (water molecule has a bent shape). The two base vertices of the face of the triangle are positively charged, that's because hydrogen is less electronegative than oxygen and, hence, the two hydrogen atoms are partially positively charged in a water molecule.
Oxygen is more electronegative than hydrogen meaning it has a greater electron-withdrawing force, so electrons are closer to oxygen within the O-H bonds. Oxygen, as a result, becomes partially negatively charged, so it's our negative pole of the magnet.
