Which statement about silver (ag) metal is least reliable? a. silver metal may be useful in medicine in the future. b. silver atoms commonly form ions with a +1 charge. c. silver is a transition metal with electrons in the d shell. d. silver atoms have 47 protons in their nuclei.

This answer should be letter A. because the other ones, are true.

Explanation:

Some silver salts are really toxic to humans, such as silver nitrate. If you are exposed to high concentrations of steam it may cause dizziness or breathing difficulties.  Eating food with silver may cause vomiting or diarrhea. For me it's hard to think that in the future silver will has healthy benefits.

for points guys

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
