PLZ HELP ON TIMER WILL GIVE BRAINLIEST How does technology limit the future of space exploration?

There are too many devices in space interfering with taking correct measurements.

Scientists cannot make contact with older satellites in outer space.

Scientists are able to work both with current and future technology.

Scientists must first develop certain technologies before missions can be completed.

b. examine and describe cells

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
