Why does radium substitute for calcium in bones?
Calcium and radium are in the same group of the periodic table of Mendeleev (group 2, alkaline earth metals); consequently calcium and radium has similar chemical properties and can be interchangeable in some situations.
Is zirconium in the same family as titanium?
Zirconium and titanium are in the group 4 (titanium group) of the periodic table of Mendeleev.
What element have chemical properties similar to magnesium?
Beryllium, Calcium or any other element within the same family or group (vertical column on the periodic table)
Are Potassium and Calcium in the same family in the periodic table of elements?
Yes. They are because they are both are in the same group and are metals.
Which element has chemical properties most similar to those of the element calcium?
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
Why does radium substitute for calcium in bones?
Calcium and radium are in the same group of the periodic table of Mendeleev (group 2, alkaline earth metals); consequently calcium and radium has similar chemical properties and can be interchangeable in some situations.
Is zirconium in the same family as titanium?
Zirconium and titanium are in the group 4 (titanium group) of the periodic table of Mendeleev.
Why did Mendeleev put bromine and chlorine in the same group on the periodic table?
They have similar properties.
Are barium magnesium potassium and calcium all in the same group?
No. Barium and magnesium and calcium are in group 2A but potassium is in group 1A.
Do elements in the same group or period have similar properties?
Elements of same group have the same number of valence electrons and hence have similar properties.
Did mendeleev group the elements by density?
Chemistry books say that he grouped the elements by atomic weight. That is not the same as density.
What elements did Mendeleev group with lithium in his periodic table?
alkaline metal group(or the group 1 elements, except for hydrogen(H), which is a group 1 element but not an alkali metal) - lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
Which is The lightest element with properties similar to calcium?
Beryllium (Be). This is because on the periodic table Be is located in the same group (column) as Calcium and is the highest element in that column. Elements of the same group have similar properties and their masses decrease the higher they are in the group.
What element have chemical properties similar to magnesium?
Beryllium, Calcium or any other element within the same family or group (vertical column on the periodic table)
Which element is in the same group as Al aluminum?
B (boron) apex
Are Potassium and Calcium in the same family in the periodic table of elements?
Yes. They are because they are both are in the same group and are metals.
Mendeleev noticed that if he organized the elements by atomic weight certain patterns emerged. For instance elements in the same group (family) appeared to have the same?
These elements have similar chemical properties.
