Which event would be impossible to explain by using John Dalton's model of the atom? O An iron atom emits particles when it is struck by light.
O An oxygen atom combines with two hydrogen atoms to form water.
O An acid reacts with a base to form salt and water.
O The atoms in sodium metal react with water.

Option A

Explanation: an iron atom emits particles when its struck by light.

The answer is A

Explanation:

Just did the quiz on EDGE 2020

Hope this helps :)

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
