The negatively charged ion among the options you provided is "chloride." Chloride (Cl⁻) is the anion derived from chlorine when it gains an electron. The other terms listed either refer to neutral molecules (chlorine) or specific polyatomic ions (chlorate and chlorite).
Based on the naming rules for ions, which of the following is a negatively charged ion (not a polyatomic ion)?(1 point) Responses chlorite chlorite chloride chloride chlorate chlorate chlorine

When moving across a period from left to right in the periodic table (excluding transition elements), the trend that occurs is that valence electrons increase by one. Each subsequent element has one more proton and one more electron than the previous element, and as you move across the period, the additional electrons are added to the same outer energy level.
Which information about an atom can a period number give you?(1 point) Responses the ionic charge it forms the ionic charge it forms the number of valence electrons it has the number of valence electrons it has how many bonds it will make how many bonds it will make how many energy levels it has
The correct response is how many energy levels it has. The period number of an element in the periodic table indicates the highest principal energy level that contains electrons in that atom. For example, elements in period 1 have one energy level, while elements in period 2 have two energy levels, and so on.
Fluorine has 7 valence electrons. Which charge is its ion likely to have?(1 point) Responses 1– 1– 5- 5- 1+ 1+ 5+
Fluorine has 7 valence electrons and is likely to gain 1 electron to achieve a stable octet. As a result, the charge of its ion is likely to be 1- (F⁻).
Use the list to answer the question. potassium, Group IA calcium, Group IIA iodine, Group VIIA neon, Group VIIIA Which two elements in the list would bond together based on their ionic charges? (1 point) Responses potassium and iodine potassium and iodine calcium and neon calcium and neon potassium and neon potassium and neon calcium and potassium
The two elements in the list that would bond together based on their ionic charges are potassium and iodine.
Potassium (K) is in Group IA and has a charge of +1 (it loses one electron), while iodine (I) is in Group VIIA and has a charge of -1 (it gains one electron). The +1 charge from potassium can balance the -1 charge from iodine, allowing them to form an ionic bond.
