medical doctors sometimes advise patients to reduce the amount of sodium (na) they consume in the form of table salt. these patients may then change to consuming a type of salt that contains potassium (k) instead of na. based on the periodic table, which statement best explains why patients could replace na with k?\na they have the same number of protons.\nb they have similar properties.\nc they are similar in color.\nd they are the same size.
Answer
# Brief Explanation:
Sodium (Na) and potassium (K) are in the same group (Group 1 - alkali metals) in the periodic table. Elements in the same group have similar chemical properties due to the same number of valence electrons. This similarity in properties allows patients to replace Na with K in some dietary - related situations.
# Answer:
B. They have similar properties.
