On the periodic table, elements that commonly form cations are typically found in which region?

• A. On the left side and in the center (groups 1, 2, and transition metals)
• B. Only in the bottom two rows (lanthanides and actinides)
• C. On the right side (groups 16, 17, and 18)
• D. Evenly distributed throughout all groups

Answer: (A)

Verified step by step guidance

1. Recall that cations are positively charged ions formed when atoms lose electrons.
2. Understand that elements tend to lose electrons if they have relatively few electrons in their outermost shell, making it easier to achieve a stable electron configuration.
3. Identify that elements in groups 1 and 2 (the left side of the periodic table) have 1 or 2 valence electrons, which they readily lose to form cations.
4. Recognize that transition metals (the center of the periodic table) also commonly form cations by losing electrons from their outer s and d orbitals.
5. Conclude that elements that commonly form cations are typically found on the left side and in the center of the periodic table, specifically groups 1, 2, and the transition metals.
