Which statement is most likely true Ernest Rutherford’s experiment led?

Which statement is most likely true? Ernest Rutherford’s experiment led to the nuclear model of the atom. Ernest Rutherford’s experiment established the plum pudding model of the atom. Robert Millikan’s postulates form the most accepted theory for the atomic structure.

Which scientist is credited with developing the first scientific atomic theory quizlet?

Dalton was able to develop his atomic theory because of the large advancement of science in his time.

Which conclusion could be made from Ernest?

Which conclusion could be made from Ernest Rutherford’s gold foil experiment? Atoms are made up of mostly empty space. Atoms are mainly solid and block alpha particles. The volume of the nucleus is large compared to the rest of the atom.

Which conclusion could be made from Ernest Rutherford’s gold-foil experiment?

Rutherford’s gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.

Which statement about the electron cloud model is true?

Which statement about the electron-cloud model is true? It is the currently accepted atomic model. Which atomic model states that it is impossible to know the exact location of electrons around the nucleus? The Bohr model of the atom explained why emission spectra are discrete.

What statements are part of the early atomic theory?

Dalton’s Atomic Theory

Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass. Compounds are produced through different whole-number combinations of atoms.

Where did Rutherford conclude that most of the mass of the atom was found?

the nucleus
He concluded that all of the positive charge and the majority of the mass of the atom must be concentrated in a very small space in the atom’s interior, which he called the nucleus. The nucleus is the tiny, dense, central core of the atom and is composed of protons and neutrons.

Which observation by Ernest Rutherford and his students refuted the plum pudding model ?( 1 point?

When Rutherford shot α particles through gold foil, he found that most of the particles went through. Some scattered in various directions, and a few were even deflected back towards the source. He argued that the plum pudding model was incorrect.

Which statement according to Dalton’s atomic theory was he wrong about?

The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects.

Which of these situations most likely produces a photoelectric effect?

Hence, you conclude that the light with more energy (the blue light) either dime or bright will most likely produce the photoelectric effect. That is why the correct options are: shining dim blue light on a strip of metal, and. shining bright blue light on a strip of metal.

Is it true that electrons orbit the nucleus in defined paths?

Electrons orbit the nucleus in specific, defined paths. Each path has a specified energy. Electrons are embedded in a mass of positively charged matter. … The energy of the emitted electrons depends on the energy of the light, not its intensity.”

Which of the following statements about isotopes is true?

Which of the following are true statements regarding isotopes? Isotopes have the same number of neutrons but a different number of protons. … Isotopes are variations of the same chemical element. Isotopes have an equal number of protons and an equal number of neutrons.

What is true about Dalton’s atomic theory?

The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties. The third part says compounds are combinations of two or more different types of atoms.

Which of the following statements about subatomic particles is true?

The true statement about subatomic particles is A) A neutral atom contains the same number of protons and electrons.

Which of the following statements is true about the two isotopes of carbon C613 and C612?

Which of the following statements is true about the two isotopes of carbon C613 and C612? They have different numbers of neutrons.

Which of the following is true for an atom?

Atoms are always neutral in nature. … Atoms consist of three basic particles, protons, electrons, and neutrons. The nucleus (center) of an atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and they contain the electrons.

Which is true about elements or isotopes with stable nucleus?

The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) … Stable isotopes do not decay into other elements. In contrast, radioactive isotopes (e.g., 14C) are unstable and will decay into other elements.

Which of the following is true about carbon-12 and carbon-14?

Carbon-12 and carbon-14 are two isotopes of the element carbon. The difference between carbon-12 and carbon-14 is the number of neutrons in each of their atoms. … Atoms of both isotopes of carbon contain 6 protons. Atoms of carbon-12 have 6 neutrons, while atoms of carbon-14 contain 8 neutrons.

Which of the following is an accurate statement about the neutron?

Which of the following is an accurate statement about the neutron? Its mass is greater than the mass of the proton plus electron.

Which of the following is not true about the nature of the subatomic particles in an atom *?

The statement that is not true about subatomic particle is that all electrons and atom contain the same amount of energy.
