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. Web22 sep. 2024 · In this video we’ll use the Periodic table and a few simple rules to find the number of protons and electrons for the Beryllium ion (Be2+). From the Periodic Table we can find the element...

WebElectron Configuration for Fe, Fe2+, and Fe3+ (Iron and Iron Ions) In writing the electron configuration for Iron the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Iron go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. 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.
