Answer:
Belong to the same group.
Explanation:
Different elements are most likely to react in similar ways when they belong to the same group.
This is because the elements in the same group always have similar number of valence electrons which implies that they all have the same number of electrons in their outermost shell. For example,barium (Ba), beryllium (Be), calcium (Ca), magnesium (Mg), radium (Ra), strontium (Sr) all have 2 electrons in their outermost shell and thus they belong to group 2 of elements which are known as Alkaline earth metals and they all tend to react in the same manner with other substances
A proton has about 1836 times the mass of an electron. The best estimate of physicists is that the radius of a proton is about 8×10-16m and the radius of an electron is about 10-16m . If they are correct, then a proton has about ten times the diameter of an electron
Answer:
If there is only one atom for the first element in the chemical formula, the prefix mono is typically omitted from the name. For example, CO is carbon monoxide, not mono carbon monoxide. ... Thus the chemical formula for carbon dioxide is CO2, not C1O2.
