6.7 mass because 1 atom equals 6.3 but if u add 4 it would be 6.7
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 :
- Metalloids look like metals but behave largely like non-metals.
- Metalloids are solid, brittle and lustrous.
- Metalloids has ability to conduct electricity.
Therefore, Group 14 elements are likely to have substances that have both metal and non-metallic properties.
Answer:
This is a reversible change. Similarly, if you boil water, it evaporates and becomes water vapor. When you cool this vapor down, it turns back to water. A change which cannot happen backward, that is, it cannot be reversed is called an irreversible change.
Explanation:
1.Molar mass is the mass of one mole per single element while atomic mass is the mass of an atom at rest or is the number of protons and neutrons.
2.Molar mass is measured in grams per mole while atomic mass is “unitless.”
3.Atomic mass is measured via mass spectrometry while molar mass is computed via atomic weight.
