A statement that describes the distribution of charge in an atom? The atomic nucleus is positive.Electrons are negative. Which term describes energy stored inside the nucleus of an atom? Further explanation. An atom is the smallest material consisting of a nucleus, which contains protons, neutrons, and electrons that surround it. The Atomic Number (Z) indicates the number of protons in an atom of an element. Ionization energy is the energy required to remove an electron from a specific atom. It is measured in kJ/mol, which is an energy unit, much like calories. The ionization energies associated with some elements are described in the Table 1. The plum pudding model is one of several historical scientific models of the atom.First proposed by J. J. Thomson in 1904 soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model tried to explain two properties of atoms then known: that electrons are negatively-charged particles and that atoms have no net electric charge. Choose the statement that is false or incorrect. ... addition of a carbon atom between each two units ... Choose the answer that best describes HCO3-. A) common in ... Which statement describes the elements in period 3 each successive element has a greater atomic radius each successive element has a lower electro? We need your help! Please help us improve our content by removing questions that are essentially the same and merging them into this question. The atom, as described by Ernest Rutherford, has a tiny, massive core called the nucleus. The nucleus has a positive charge. Electrons are particles with a negative charge. Electrons orbit the nucleus. The empty space between the nucleus and the electrons takes up most of the volume of the atom. The atom is a hard sphere—> most of the atom is empty space—> electrons exist in orbitals outside the nucleus An atom is electrically neutral because the Number of protons equals the number of electrons Study 19 Exam 3 flashcards from Kara P. on StudyBlue. blount and colleagues predicted that if cit+ e. coli were the result of multiple sequential mutations, then samples of e. coli from later generations would be more likely to give rise to cit+ cells. in other words, a mutation likely occurred in later generations that predisposed e. coli cells to become cit+. imagine that blount and ... Further explanation. An atom is the smallest material consisting of a nucleus, which contains protons, neutrons, and electrons that surround it. The Atomic Number (Z) indicates the number of protons in an atom of an element. 2. An atom can be excited by emitting light energy. 3. As the energy of electromagnetic radiation increases, its frequency increases. 4. The frequency and wavelength of light are inversely proportional. a. 2 and 3 b. 1 and 3 c. 1 and 2 d. 3 and 4 e. 2 only 3. Which statement best describes the path of an electron as it moves in a p orbital? a. Which statement describes the elements in period 3 each successive element has a greater atomic radius each successive element has a lower electro? We need your help!

What statement best describes your view of today’s world 74 years after the first atom bomb? Choices The United States and allies are much safer, thanks to having nuclear weapons. Mar 17, 2011 · In the Nucleus of an atom there are protons and neutrons. Protons hold a positive charge, which (in atoms with no charge) is balanced by electrons. Neutrons act as 'nuclear glue', they hold the protons in the nucleus together, stopping the atom from decomposing (losing protons). Jan 27, 2020 · The modern model of the atom is based on quantum mechanics. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version. Each of the following describes an "Atom 1" and an "Atom 2." In which case are the two atoms different isotopes of the same element? Atom 1: nucleus with 6 protons and 8 neutrons, surrounded by 6 electrons; Atom 2: nucleus with 7 protons and 8 neutrons, surrounded by 7 electrons 7 Which statement describes a chemical property of hydrogen gas? (1) Hydrogen gas burns in air. (2) Hydrogen gas is colorless. (3) Hydrogen gas has a density of 0.000 09 g/cm 3 at STP. (4) Hydrogen gas has a boiling point of 20. K at standard pressure. 1: chemical properties involve reactions: 8 Which element has the greatest density at STP? Which statement best describes how public officials use technology to benefit individual citizens? Definition If a scientific model predicts that a hurricane will hit a specific area, public officials will know which people are in the biggest danger and will order evacuations. The electron cloud model best describes the organization of electrons around the nucleus of an atom. What best describes rutherfords model of the atom? It is like a huge stadium with a positively ... Niels Bohr developed a quantum model for the hydrogen atom. The lowest possible energy state of a molecule or atom is called its ground state. A gamma ray of wavelength 1.00 × 10 –8 cm has enough energy to remove an electron from a hydrogen atom. Which of the following best describes an orbital?

D. 9.Which statement describes the distribution of charge in an atom? A)passed through the foil B)remained trapped in the foil C)were deflected by the nuclei in gold atoms D)were deflected by the electrons in gold atoms 10.The gold foil experiment led to the conclusion that each atom in the foil was composed mostly of empty Which of the following best explains what is happening when an atom emits light? Heat energy is converting a neutron into a proton and an electron, which is ejected into the orbit of the nucleus, releasing light energy. Further explanation. An atom is the smallest material consisting of a nucleus, which contains protons, neutrons, and electrons that surround it. The Atomic Number (Z) indicates the number of protons in an atom of an element. Which statement best describes an O 3 molecule?
