“…3(a, b), XRMPA was done. Table 1 provides the element compositions measured in regions 17 ( Note that both parts of the dark particle contain only light elements, such as 6 C, 7 N↑, 8 O, 9 F↑, 10 Ne↑, 11 Na, 12 Mg, 13 Al, 14 Si, 15 P, 16 S, 17 Cl, 18 Ar↑, 19 K, 20 Ca, and a heavier metal 29 Cu. Here is a series of elements with a nucleus charge change by ΔZ = 1 from Z = 6 (carbon) to Z = 20 (calcium), where the volatile elements 7 N↑, 9 F↑, 10 Ne↑, 18 Ar↑, which could not have formed any chemical compounds, were not detected.…”
