Calcium, period 4 group 2, very reactive
Fluorine because it is in the same group (group 17) as Bromine therefore it has the same chemical properties
Elements similar to chlorine will be located in the same group(17).
The chemical properties of calcium are most similar to (in between) the chemical properties of magnesium and strontium.
all group 17 atoms are similar, so Bromine and Iodine would also be similar. Astitaine is much less well known but would also be somewhat similar as well.
Chlorine, Bromine, and Iodine. They are all in the same periodic group.
calcium
Fluorine or Bromine have similar properties to chlorine because both are halogens.
Magnesium is a metallic element with chemical properties similar to calcium.
Fluorine because it is in the same group (group 17) as Bromine therefore it has the same chemical properties
The chemistry of meitnerium is not known today; it is possible that the chemical properties will be similar to properties of iridium which is not a reactive metal.
It is supposed that the chemical properties of roentgenium are similar to the properties of silver.
The chemical properties of meitnerium are similar to properties of iridium, his homologue.
Magnesium is a metallic element with chemical properties similar to calcium.
