WebbBecause this element is located in Group 17, or 7A, on the periodic table, it will ionize to form an anion with a –1 charge. Therefore, the resultant ion is symbolized as I– 1 and is named the iodide ion . Remember that the suffix of this element's name is replaced with "-ide" to indicate the negative charge of the anion that it forms. Webb3 aug. 2024 · No, they should be placed in the same slot (or position) because the periodic table is based on the atomic numbers of the elements.

The most common wrong answer is hydrogen. Everyone thinks hydrogen is the smallest atom in terms of size in the whole periodic table because it has only one proton. Helium has two protons so shouldn’t it be double the size no that’s wrong. Helium is the smallest atom. How is it possible? fisher enzyme assay
