Question

using the periodic table, which statement is correct?
a. sodium (na) has more protons than carbon (c).
b. hydrogen (h) has more protons than helium (he).
c. iron (fe) has more protons than silver (ag).
d. oxygen (o) has more protons than chlorine (cl).

Explanation:

• Option A: Sodium (Na) has an atomic number of 11 (number of protons = 11), carbon (C) has an atomic number of 6 (number of protons = 6). So, Na has more protons than C.
• Option B: Hydrogen (H) has an atomic number of 1 (number of protons = 1), helium (He) has an atomic number of 2 (number of protons = 2). So, H has fewer protons than He.
• Option C: Iron (Fe) has an atomic number of 26 (number of protons = 26), silver (Ag) has an atomic number of 47 (number of protons = 47). So, Fe has fewer protons than Ag.
• Option D: Oxygen (O) has an atomic number of 8 (number of protons = 8), chlorine (Cl) has an atomic number of 17 (number of protons = 17). So, O has fewer protons than Cl.

Answer:

A. Sodium (Na) has more protons than carbon (C)
