The number of protons in an atom is equal to the atomic number is 50. The sum of the Neutrons and Protons is the Atomic Mass is 125. Neutrons + Protons = 125. Plug in for the protons (50) Neutrons +(50) = 125. Then, the number of Neutrons will be 75. Assuming the atom is not an ion, the amount of electrons is equal to the number of protons ...
The atomic number of tin is 50, and an isotope of tin with 68 neutrons has a mass number of 118. Explanation: To determine the number of moles of tin in 325.0 grams, we need to use the molar mass of tin. From the periodic table, the average atomic mass of tin (Sn) is 118.7 g/mol. Therefore, the molar mass of tin is also 118.7 g/mol.
- The atomic number of the resulting atom will decrease by 1 (from 50 to 49), while the mass number remains 100. - This process forms a new element with atomic number 49. In summary, when Cardinalium-100 (atomic number 50) undergoes different radioactive decays: - Alpha decay reduces the atomic number by 2 and the mass number by 4.
An atom of tin with an atomic number of 50 and a mass number of 119 will have 50 protons, since the atomic number is the number of protons in an atom's nucleus. A neutral atom of tin will also have 50 electrons, because in a neutral atom, the number of protons equals the number of electrons.
The atomic number refers to the number of protons in the nucleus of the atom, and in a neutral atom, it also equals the number of electrons. Therefore, a neutral tin atom has 50 protons and 50 electrons. The mass number, on the other hand, is the sum of protons and neutrons in the nucleus. Therefore, to find out the number of neutrons, you have ...
A model of tin, an element with the atomic number 50, is shown here. The valence electrons are modeled here in this image. Which statements are supported by the information in the model? Select ALL That apply. A) Tin needs four more electrons to complete its outer shell. B) Tin has no neutrons in the nucleus, as is shown in the model.
The atomic symbol represents the element, while the mass number is the sum of protons and neutrons in the nucleus of an atom. In this case, the element with 50 protons is tin (Sn). To find the mass number, you add the number of protons (50) and the number of neutrons (64), which gives a total of 114. Therefore, the correct answer is 114Sn ...
Identify the atomic number of tin (Sn): - Tin has an atomic number of 50. This number indicates that it has 50 electrons. 2. Determine the closest preceding noble gas: - To simplify the electron configuration, we use the electron configuration of the nearest noble gas that has fewer electrons than tin.
The atomic number of an element is the number of protons in its nucleus. Here, the element has 50 protons. Therefore, its atomic number is 50.The atomic mass of an element is the sum of the number of protons and neutrons in its nucleus. Here, the element has 50 protons and 68 neutrons.
The correct answer is 50, 50, and 70. In an element, there are the following things:-Electrons; Protons; Neutrons; In elements, the number of protons and electrons are the same. hence, the number of electrons and protons in an element is 50. The neutrons are defined as the proton minus mass number. Hence, the number of neutrons is 120-50=70
