J. J. Thomson discovered electron by performing an experiment using cathode ray tubes. High voltage across is applied across two electrodes at that causes a beam of particles to flow from the the negatively-charged electrode that is cathode to the positively-charged electrode that is anode. Properties of the particles, are tested using two oppositely-charged electric plates around the cathode ray. The cathode ray was deflected away from the negatively-charged electric plate and towards the positively-charged plate. This indicated that the cathode ray was composed of negatively-charged particles. And these negatively charged particles are called electrons.
B. 35.45 ! Hope this helps
I know the answer. It is 2 straight chains. lLOL
Answer: C) Both are made up of monomers that are linked by covalent bonds
Explanation: Polymers are large molecules which are formed by combination of small repeating units called as monomers.
Natural polymers are found in nature such as cellulose whereas synthetic polymers are synthesized in laboratories such as Nylon 6,6.
All the polymers, whether natural or synthetic are made up of monomers and are joined by covalent bonds.
Explanation:
4.hydrogen is able to accept or donate electrons,so it is the most versatile storm I the periodic chart
