Ion with charge of -2
Web30 mrt. 2024 · Which group will form a 2+ ion? The elements that are most likely to form 2− ions are the group 16 elements. Their atoms have 6 valence electrons, and need 2 more to have a full valence shell of 8 electrons in order to become stable. When they gain 2 electrons in order to have 8 valence electrons, an octet, they gain a 2− charge. WebBecause the charge on the chloride ion is −1 and the charge on the calcium ion is +2, for example, consistent with their positions in the periodic table, simple arithmetic tells you that calcium chloride must contain twice as many chloride ions as calcium ions to maintain electrical neutrality. Thus the formula is CaCl 2.

Web7 aug. 2024 · What is the charge of the phosphate group? Each phosphate is a PO 4 (oxygen has a charge of -2 and there are 4 of them, for a total of -8, and P has a charge of +5, so the net charge on the phosphate group is -3. If free H atoms, which are +1, get added to the O atoms that aren’t bonded to two things, then the net charge is zero.) Web28 jul. 2024 · An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. Share this post Post …
