Answer:
atoms form bonds by donating, accepting or sharing electrons with other atoms in order to complete their valence shell electrons
hence , C. Bonding gives an atom the same number of protons as a noble gas.
Explanation:
i hope it helped
Answer:
Option B. Coulomb Repulsion
Explanation:
The reason for the heavy nucleus not being able to follow the trend or the N= Z line is because of the fact that as the atomic number, Z of an atom increases, the number of protons inside the atom also increases. Since the neutrons are charge less particles whereas the protons are positively charged particle and hence as these increases in number there is an increase in the repulsive force between the like charges, i.e., positively charged protons which is Coulomb repulsion.
It would take 500 seconds, because 2500 divided by 5 is 500
Pb, if compared to Ca it is less reactive and it is a transition metal, and is highly stable alone.
1c. The goal of technology is to improve how people live. For example a toothbrush helps prevent cavities and buildup on our teeth.
2a. Science and technology both help improve our lives. Science gives us the knowledge we need to create technology.
2b. A human prosthetic is an example of technology.
2c. Prosthetics are created though scientific study and research. Technology is used to create the material prosthetics are made of and to help design the prosthetics.
3a. Benefits of pesticides: Keeps bugs away from crops, higher crop yields.
Negatives:
pollution, harmful to health
I got all of them except the last one
