Which is a way that the model of the atom became stronger through new experiments? (1 point) a
New technology allowed scientists to show that the atom is indivisible.

b
It took new data to show that positive charge is not spread throughout an atom.

c
By deflecting alpha particles, Rutherford first observed the neutron.

d
The neutron could not be detected until Cathode–Ray Tubes were invented.

Explanation:

Key points

J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons.

Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."

Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.

Based on these results, Rutherford proposed the nuclear model of the atom.

answer:

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

0.88m hope i am correct : )
