The structure of the atomOn the basis of Rutherford's experimental observations, which of the following statements predicts the
structure of the atom?1. In an atom, negatively charged electrons are small particles held within a positively charged sphere.2. In an atom, negatively charged electrons are dispersed in the space surrounding the positively charged nucleus of an atom.3. In an atom, all of the positive and negative charges are randomly distributed.4. In an atom, most of the mass and the positive charge are located in a small core within the atom called the nucleus.2. In an atom, negatively charged electrons are dispersed in the space surrounding the positively charged nucleus of an atom.4. In an atom, most of the mass and the positive charge are located in a small core within the atom called the nucleus.
In rutherford experiment he bombarded highly energetic alpha particles towards the gold foil
He observed that most of the alpha particles pass through the foil without any deviation while very few of the alpha particles are there which reflect back to its own path
while very less in number was there which were deflected from there path
so he concluded that the positive charge of atom is concentrated inside the nucleus and it is small space in tom and electrons are surrounded them
so correct answer would be
4. In an atom, most of the mass and the positive charge are located in a small core within the atom called the nucleus.
Answer:As an object speeds up, the total energy increases / decreases / remains the same. As an object slows down, the total energy increases / decreases / remains the same.
