e. Sr, Se, Ne

f. Fe, P, O

Step 1 of 4

(a) Atomic radius increases going right to left and top to bottom on the periodic table. The atoms S, Se, and Te are in the same column, so the smallest will be at the top, and the size will increase going down. Therefore, the order of size increasing for following atoms is s,se,te

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
