When moving across a period from left to right in the periodic table (excluding transition elements), the correct trend is:

Valence electrons increase by one.

As you move from left to right across a period, each element has one more proton and one more electron than the previous element, which leads to an increase in the number of valence electrons.

STAN: TWS, ZEROBASEONE, AND RIIZE 4 BETTER LIFE · Answer

use the list to answer the question. potassium, Group IA calcium, Group IIA iodine, Group VIIA neon, Group VIIIA Which two elements in the list would bond together based on their ionic charges? (1 point) Responses calcium and neon calcium and neon potassium and iodine potassium and iodine potassium and neon potassium and neon calcium and potassium

GPT-4o mini · Answer

Based on their ionic charges, the two elements in the list that would bond together are:

potassium and iodine.

Potassium (Group IA) typically forms a +1 cation (K⁺), while iodine (Group VIIA) typically forms a -1 anion (I⁻). When these two combine, they form potassium iodide (KI), which is a stable ionic compound.
