Chlorine, Bromine, and Iodine. They are all in the same periodic group.
Element A and element B are the most likely to have similar properties because they belong in the same family, because if you know an element's family you can tell the number of valance electrons and the elements they react with. In periods, the properties are not alike, they slowly change in a pattern.
The halogens are: fluorine, chlorine, bromine, iodine, and astatine - although astatine only occurs in extremely minute quantities as part of the decay chain of some radioactive elements like uranium and thorium.
There are three lone pairs present in chlorine atom
elements in a marble chip is not far fetched. They are: calcium, carbon and oxygen. otherwise known as CaCO3(note the three is below and not on the same line.
The constituent elements of calcium carbonate are calcium, carbon, and oxygen.
Bromine, iodine, and fluorine are three elements that exhibit similar chemical properties to chlorine due to belonging to the same halogen group in the periodic table. They all have seven valence electrons, which contributes to their reactivity and ability to form compounds with other elements.
The nonmetal in period three with properties similar to iodine is chlorine. Chlorine is in the same group (halogens) as iodine and shares similar chemical properties such as being highly reactive and forming compounds easily.
Three elements that have similar chemical properties to oxygen are sulfur, selenium, and tellurium. These elements belong to the same group as oxygen in the periodic table and have similar electron configurations, which influence their reactivity and chemical behavior. Additionally, they can form similar types of chemical bonds with other elements.
Three non-metals that share very similar chemical properties are nitrogen, phosphorus, and arsenic. They are all located in the same group on the periodic table (Group 15), known as the nitrogen group, and exhibit similar reactivity and bonding characteristics.
Iron , cobalt and Nickel families of periodic table show the similar properties. these families are in three different columns but are considered as one group.
Magnesium, strontium , and barium belong to group 2A of the periodic table. These have two valence electrons in their outermost shell. So these three elements have similar chemical properties. But the other given elements do not lie in same group so they have different chemical properties.
Newland, Moseley, , Dobereiner, Mendeleeff...
dabbing on them haters which I mean is A answer choice A
Fluorine, chlorine and bromine are corrosive.
chlorine, fluorine and carbon
It has a pungent odour. It is colourless. It is a proton acceptor.
it tells us that their chemical properties are similar, and in many cases follow a trend.
