I am going to say C. it has to do with the angles
Answer:
5. Atoms with high ionization energies and high electron affinities have low electronegativities.
Explanation:
Ionization energy is the minimum amount of energy which is required to knock out the loosely bound valence electron from the isolated gaseous atom.
Electron affinity is the amount of energy released when an isolated gaseous atom accepts electron to form the corresponding anion.
Electronegativity is the tendency of an atom in a bond pair to attract the shared pair of electron towards itself.
Low ionization energies as well as low electron affinities mean the atom has low effective nuclear charge, which results in the less attraction of the valence electrons by the atom and thus, low electronegativity.
Sodium because according to the atomic size trend of the periodic table. Elements further to the left are bigger while elements tot he right are smaller. This is also do to their charges, Na has a +1 charge meaning it doesn’t pull the electrons as close as the Mg does with its +2 charge.
Answer:
the protons
Explanation:
the number of protons is constant for each sample of the element. If the number of protons differs, then it is a different element.
According to Newton's laws, the relationship between acceleration and mass and force is F=ma.
40kg×7.5m/s²=300N
so the answer is 300N.
