About this reader
This NGSS-aligned science reading passage explains how many valence electrons chlorine has and why that makes it such a reactive element. Chlorine has 17 total electrons, with 7 in its outermost shell, making it one electron short of a full shell. The passage discusses the octet rule, chemical bonding, and how chlorine combines with other elements like sodium to form compounds such as salt (NaCl). This passage supports NGSS standard MS-PS1-1 by helping students understand atomic structure, periodic table grouping, and the role of electrons in chemical behavior. Multiple-choice questions reinforce key vocabulary, science reasoning, and reading comprehension, making it ideal for middle school learners.
