How reactive is an atom of sodium(na) and why? question 1 options: sodium (na) is not very reactive because it does not have a full valence shell. sodium (na) is very reactive because it does not have a full valence shell. sodium (na) is very reactive because it does not have enough protons in the nucleus. sodium (na) is not very reactive because it can only bond with chlorine (cl) to become salt. i need this asap !

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?

The law of reflection states that the angle of reflection is equal to the angle of

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
