Elements from the group 2 of the periodic table form cations.
nothing
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
Groups 4 (can make positive and negative ions), 5, 6 and 7.
Most negative ions are found in elements on the far right side of the periodic table. But, if you have a decent table, you can find the possible ionic charges for each element. Look for the negative numbers.
Groups 4 (can make positive and negative ions), 5, 6 and 7.
Elements that will form anions are on the right side of the periodic table, except for the noble gases in group 18, which don't form ions.
cations and anions
The periodic table table has elements arranged in increasing order of the atomic number. NaCl is a salt derived from sodium and chloride ions. Neither ions nor compounds are listed in periodic table. The elements involved in producing the salt are sodium (period 3 group 1) and chlorine (period 3 group 17).NaCl is made up of two elements: sodium and chlorine. Sodium is present in group-1. Chlorine is present in group-17.
These cations have the electrical charge +1.
All the elements in the periodic table of elements are electrically neutral; they do not have charges as elements, although they have the potential to engage in chemical reactions that will turn them into charged ions, in most cases. The different groups tell you what kinds of chemical reactions the elements are capable of, not what kind of charge they have.
Cl is the symbol of chlorine on the periodic table. Cl- stands for chloride anion and is not seen on the periodic table, as periodic table lists elements and not ions.
