Who discovered the positive charge of a nucleus?
Ernest Rutherford is credited with discovering the positive charge of a nucleus through his famous gold foil experiment in 1909. This experiment showed that most of the mass and positive charge of an atom is concentrated in a small, dense nucleus at its center.
What main feature of Thomson atomic model was charged after Rutherford discoveries?
The main feature of Thomson's atomic model that was changed after Rutherford's discoveries was the location of the positive charge in the atom. Rutherford discovered that the positive charge was concentrated in a small nucleus at the center of the atom, rather than being spread out evenly throughout the atom as Thomson had proposed.
How did the discovery by Rutherford change Thomson's theory?
Rutherford's discovery of the nucleus in an atom challenged Thomson's "plum pudding" model, which suggested that the positive charge and electrons were dispersed evenly throughout the atom. Rutherford's experiment showed that the positive charge was concentrated in a small, dense nucleus, with electrons orbiting around it. This led to a new understanding of the atom's structure and the development of the nuclear model.
Why did Rutherford change Thomson's model of the atoms?
According to his Thompson's model, an atom was a sphere of positive matter that held electrons, so Rutherford discovered that an atom has a nucleus and that the nucleus contains most of the matter of the atom. Also that the atom has electrons, protons, and neutrons surrounding it.
What did Rutherford discover that Thomson did not understand?
That most of an atom's mass was packed in a central nucleus
What best describes Rutherford's model of an atom?
Rutherford imagined the atom to be a particle with a thickly concentrated positive nucleus and electrons moving around it.
Which statement correctly describes the graph of g(x) if g(x) f(x - 6)?
The graph of g(x) is the graph of f(x) shifted 6 units in the direction of positive x.
What describes Rutherfords model of an atom?
Rutherford imagined the atom to be a particle with a thickly concentrated positive nucleus and electrons moving around it.
There is a relationship between smoking cigarettes and getting emphysema This statement describes?
A positive correlation, nothing more.
Which statement most accurately describes a characteristic of sarcasm in literature?
Sarcasm sounds positive but is meant to be the opposite.
What is the Difference between positive and normative science?
A Normative Theory expresses a judgment about whether a situation is desirable or undesirable, and is based upon some moray or standard. The world would be a better place if the moon were made of green cheese, is a normative statement because it expresses a judgment about what ought to be. Notice that there is no way of disproving this statement. If you disagree with it, you have no sure way of convincing anyone, who believes the statement, that it is incorrect.A Positive Theory expresses an opinion on a condition, assuming what is, and that contains no indication of approval or disapproval and is not based on any standard. Notice that a positive statement can be incorrect. The moon is made of green cheese, is incorrect, but it is a positive statement because it is a statement about what exists.
Who discovered the positive charge of a nucleus?
Ernest Rutherford is credited with discovering the positive charge of a nucleus through his famous gold foil experiment in 1909. This experiment showed that most of the mass and positive charge of an atom is concentrated in a small, dense nucleus at its center.
Which statement best describes a line in slop-intercept form when the coefficient of the x-term is positive?
The line will be going 'uphill' from left to right
What did Rutherford believe in the center of an atom?
a nucleus with a positive charge
Is this a positive statement or normative statement The minimum wage creates unemployment among young and unskilled workers?
It is a positive statement.
Who atomic model determined that an atoms positive charge is concentrated in the atoms center?
The Rutherford model proposed that an atom's positive charge is concentrated in a dense center called the nucleus. This model was based on the famous gold foil experiment conducted by Ernest Rutherford in 1909.
What is an example of a positive prejudicial statement?
A positive prejudicial statement is a statement that relies on stereotypes, but does not say anything negative about the group. For example, saying Asians are good at math would be a positive prejudicial statement.
