Webb4 nov. 2024 · Here is a table of element valences. Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell.

Webb5 jan. 2024 · The sodium (Na) atom transfers one electron to the chlorine (Cl) atom, so that they both have full outer shells. Because the sodium ion has a positive charge, and the chlorine ion has a negative charge, they are attracted to each other, and form an ionic bond. When sodium loses an electron to chlorine the sodium becomes a? Webb25 mars 2024 · The outer shell of the chlorine is closer to the nucleus and it is less shielded than the outer shell of iodine. Therefore, chlorine attracts electrons. Chlorine is more reactive than iodine since chlorine can gain electrons more easily than iodine. How is chlorine more reactive than bromine and iodine? notice of intent to introduce evidence

WebbIodine (atomic symbol: I, atomic number: 53) is a Block P, Group 17, Period 5 element with an atomic radius of 126.90447. The number of electrons in each of Iodine's shells is 2, 8, … Webb24 apr. 2024 · For bromine or iodine to react, each atom needs to gain an electron to fill up its shell so that it is in a more stable state. Since bromine has fewer shells, its outer … Webb22 feb. 2024 · Step 1: Write the electron configuration of the atom in the following form: (1s) (2s, 2p) (3s, 3p) (3d) (4s, 4p) (4d) (4f) (5s, 5p) . . . Step 2: Identify the electron of interest, and ignore all electrons in higher groups (to the right in the list from Step 1).
