Which are true comparisons of alpha and beta decay? check all that apply.
a. beta radiation damages a cell more than alpha radiation.
b. beta radiation can damage a higher number of cells than alpha
radiation.
c. beta particles can travel farther than alpha particles.
d. beta particles are bigger than alpha particles.

See below  

Explanation:

A. False. Alpha radiation is more damaging to the cell than beta radiation.

B. True. Beta radiation is less damaging, but it has greater penetrating power, so it can damage more cells.

C. True. Beta particles have greater penetrating power than alpha particles.

D. False. Beta particles are electrons. Alpha particles are much larger helium nuclei.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
