An unknown element has two stable isotopes. 92.41 percent of all atoms of this element have a mass number of 7. The remaining 7.59 percent of atoms of this element have a mass number of 6. Which of the following is MOST LIKELY to be true about the average atomic mass
of the unknown element
The average atomic mass is slightly lower than 7 but much higher than 6.
The average atomic mass is 6.5
There is no way to estimate the average atomic mass without knowing the identity of the element.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or
