To find<span> the </span>valence electrons in an atom<span>, identify what group the element is in. An element in group 1A has 1 </span>valence electron<span>. For example, Li is in group 1A, so that means it has one </span>valence electron. If the element is in group 2A, then it has two valence electrons<span>.</span>
The higher the amount of protons, the higher the amount of attraction, and the higher the attraction, the higher the electronegativity. N has 7, and O has 8. Therefore Oxygen has a higher level of electronegativity
Answer:
B and D
Explanation:
it is B and D because in no gravity if you change the size of the ball it does not change anything. and if you swing fast it does not change anything but the speed. if you change the angle it is just the same modle but different angle

I think you refer to Rutherford's Gold Foil Experiment alpha particles pass through because of the enormous amount of empty space inside the atom.
>>>more details here<<<
to have its trajectory affected the alpha particle has to pass "near" the nucleus to interact with the positive charge of the nucleus.
the fact is that internally the gold atoms are basically empty space and the nucleus represents only a small portion of the entire volume. only few alpha particles pass near the nucleus
