The chemical properties of calcium are most similar to (in between) the chemical properties of magnesium and strontium.
Calcium and potassium
Fluorine because it is in the same group (group 17) as Bromine therefore it has the same chemical properties
elements in each group of the periodic table have identical chemical properties as they have the same no. of valence electrons which determines their chemical properties. since calcium is in group II of the periodic table, it has the same chemical properties as the elements in group II. Elements in group II consists of: Be, Mg, Ca, Sr, Ba, Ra Elements in the same group has different physical properties such as boiling and melting points. However there are trends of their physical properties down the group.
Potassium. Sodium is in group1 (period2) the next heaviest element is potassium (period 3). Potassium forms salts with the K+ ion.
The other members of group 17, the halogens. Specifically chlorine
Calcium and potassium
atoms in the same group are similar. calcium is in group 2, so it's similar to Be, Mg, Sr, Ba and Ra. Most similar would be Mg or Sr, which are right above and below. all group 2 atoms share a similar electron configuration
potatoe
Potassium - K
Se (Selenium)
Fluorine because it is in the same group (group 17) as Bromine therefore it has the same chemical properties
1 and 2
o, s, se
Nitrogen is very similar in chemical properties to Carbon.
Calcium is most like magnesium in its chemical bonding properties, with beryllium close behind. These are the elements respectively below and above magnesium in column 2 of a wide form periodic table.
a) nitrogen b) fluorine c) oxide iond) nitride ion e) sulfurOut of these options, the correct answer is e) sulfur. Sulfur is the chemical species that would be expected to have a properties most similar to oxygen.
The most important principle was the listing in groups, after similar chemical or physical properties.
