Answer: electron on the shell of the atom
Explanation: that what I trying to remember
Answer:
1) The risk of high cost due to increased resource requirements
2) The risk of late entry into the (a changed) market
Explanation:
The analysis being performed by the engineers = A cost benefit analysis to determine if a new technology should be developed
A cost-benefit analysis is a process of appraising or measuring the advantages, benefits of a policy, action or decision, so as to find the (equilibrium) balance point between the costs of the decision or action
The risk to be considered are;
1) The risk of high cost due to increased resource requirements
The increased cost required for the development of the new technology now which due to the unlikely existence of a similar invention in the market that will give them an advantage of increased profits
2) The risk of late entry into the (a changed) market
The changes in the consumer preferences, market landscape, and the likely introduction into the market of a similar invention by the competition in the near future which will reduce the amount of profits that can be gained from the invention
Beta radiation / decay would likely occur when the ratio of protons to neutrons is below the band of stability.
Answer:
30, 50
Explanation:
Hello,
In this since an element's atomic number is equal to the number of protons in its atom, we can infer that selenium's atomic number is 30. Moreover, due to the fact the the neutrons are equal to the atomic mass minus the atomic number or the number of protons, by knowing the number of neutrons we compute the atomic as follows:

Thus, answer is 30, 50.
Best regards.
