Question

Elements of group 4a do not commonly form ions. generally form negative ions. do not combine with other elements. generally form positive ions.

Answer 1

Elements of Group 4A typically do not form ions readily, but when they do, they generally form positive ions or cations with a +4 charge.

Step-by-step explanation:

Group 4A elements, also known as the carbon group, typically do not form ions easily. This is because the elements in this group generally have a balance between the energy required to lose or gain electrons, making the formation of ions less favorable. When these elements do form ions, they generally form positive ions or cations. Looking at the periodic table, main-group elements to the left tend to form cations with a positive charge equal to the group number. Conversely, elements to the right, particularly nonmetals, often form anions with a negative charge corresponding to the number of groups they are left of the noble gases. Group 4A elements would thus be expected to form 4+ cations if they were to form ions, which is a high charge and not commonly observed due to the energy involved in removing four electrons.

Answer 2

How does the law of conservation of mass apply to this reaction: C2H4 + O2 → H2O + CO2?
