WebAg has atomic number 47 = 47 protons and 47 electrons. mass number is 108, neutrons = 108 - 47 protons = 61 neutrons. Ag+ = 47 electrons - 1 electron = 46 electrons. Finally: 47 protons , 61 neutrons and 46 electrons. answered Apr 22, 2024 by Joshua Mwanza Gold Status (26,658 points) selected Feb 15, 2024 by ♦ MathsGee Web17 jan. 2024 · The electrons only have to be filled from left to right in exactly this order. If we were to distribute electrons unconsciously with respect to how the sub-shells are lined up, as shown in the figure above, Calcium (Ca) with atomic number 20 would have the configuration 2,8,10 (2, 2+6, 2+6+2). cannot see shared files in onedrive

WebIf the number of protons is greater than the number of electrons, the charge is positive. a. 19 protons and 18 electrons = K+ c. 35 protons and 36 electrons = Br– b. 7 protons and 10 electrons = N3– d. 23 protons and 21 electrons = V2+ 3.5 Use the identity of the element to determine the number of protons. The charge tells how many Web- Carbonate ion is a nucleophile so it would easily react with protons to form carbonic acid, H2CO3. - Now, we know that sodium hydroxide is a strong base and carbonic acid is a weak acid. - Therefore, sodium carbonate is a basic salt because it is a salt derived from a weak acid and strong base.
