0 25 kJ
O 30 kJ
O 35 kJ
O 55 kJ

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
