Which of the following groups of elements are likely to have substances that have both metal and non-metallic properties? actinides group 18 lanthanides group 14

Answer : Group 14 elements are likely to have substances that have both metal and non-metallic properties.

Explanation :

Metalloid : It is a type of element whose properties lies in between the metals and non-metals.

There are commonly six metalloids : Boron(group 13), Silicon & Germanium(group 14), Arsenic & Antimony(group 15), Tellurium(group 16).

Properties of Metalloids :

Therefore, Group 14 elements are likely to have substances that have both metal and non-metallic properties.

group 14

Explanation:

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
