10. which of the following list the elements in order, from those having the fewest protons to those having the greatest number of protons? n, p, as, sb, bi li, be, he, c, n cs, rb, po, at, rn ar, i, br, cl, f clear all

Answer

Explanation:

Step1: Recall atomic number = proton number

The atomic number of an element represents the number of protons in its nucleus.

Step2: Find atomic numbers of elements in each option

For N (7), P (15), As (33), Sb (51), Bi (83); Li (3), Be (4), He (2), C (6), N (7); Cs (55), Rb (37), Po (84), At (85), Rn (86); Ar (18), I (53), Br (35), Cl (17), F (9).

Step3: Check order of proton - number in each option

In the first option N, P, As, Sb, Bi, the atomic numbers (proton numbers) increase in order. In the second option, He should come first among these elements as it has the lowest atomic number. In the third option, the order is not from lowest to highest atomic number. In the fourth option, the order is also incorrect.

Answer:

N, P, As, Sb, Bi
