I'm pretty sure they come closer, and on the small chance i'm wrong, they separate.<span />
Answer:
Group 1 or akali metals have the greatest metallic property.
Group 17 has the lowest metallic character.
C. As you move from right to lefton the periodic table, metallic character increases which is the ability to lose electrons. Ionization energy decrease as we move from right to left on the periodic table.
Explanation:
Akali metals in group 1 have the greatest metallic property and they are the most reactive metals. Francium metal on the group has the most metallic characteristics. It is rare and very radioactive. Group 17 has the lowest metallic character. This is because while moving across the period, the number of electrons in the outermost shell increases. This make it difficult for atoms to leave see electrons and become electropositive . Group 17 has the highest tendency of accepting electrons.
Ionization energy is the energy use to remove electron from an atom in gaseous stage. Ionization energy decrease as we move from right to left on the periodic table and metallic character increases as we move from right to left on the periodic table.
Answer:
The criteria listed in order of importance are;
1) To be inflated in the event of a collision in order to protect the occupants of the front of the vehicle
2) To be able to withstand the load of the breaking force of the occupants in the front seat of the vehicle during a collision
3) To be relatively tough so as to resist being torn on impact with a sharp object
The constraints listed in order of importance are;
1) How is the model design able to sense a collision that requires the airbag to be inflated
2) The uncertainty of the load the airbag will withstand upon collision
3) The possible hazard that could be caused by the gas used to inflate the airbag
4) The usage/interaction tendency between the vehicle occupant and the airbag system
Explanation:
In order to produce an effective design, it is important to be able to foresee the possible deficiencies of an idea so as to be able to mitigate the problems before an actual incident happens.
