All atoms of the same element have the same number of ________. Do all isotopes of an element have the same atomic number? \[ \begin{align}\text{atomic number} = \left( \text{number of protons} \right) &= 3 \nonumber \\ \left( \text{number of neutrons} \right) &= 3 \nonumber\end{align} \nonumber \], \[ \begin{align} \text{mass number} & = \left( \text{number of protons} \right) + \left( \text{number of neutrons} \right) \nonumber\\ \text{mass number} & = 3 + 3 \nonumber\\ &= 6 \nonumber \end{align}\nonumber \], \[ \begin{align}\text{atomic number} = \left( \text{number of protons} \right) &= 3 \nonumber\\ \left( \text{number of neutrons} \right) & = 4\nonumber\end{align}\nonumber \], \[ \begin{align}\text{mass number} & = \left( \text{number of protons} \right) + \left( \text{number of neutrons} \right)\nonumber \\ \text{mass number} & = 3 + 4\nonumber \\ &= 7 \nonumber \end{align}\nonumber \]. Nuclei that are all isotopes of an element all have the same A. number of protons. Process of transferring data to a storage medium? Figure 14: Diagram of Tritium, 3He, All atoms are neutral with the number of protons equaling the. b) They are isotopes. Some isotopes decay very quickly into other elements and emit radiation, while other isotopes do not. All atoms of a given element have the same number of (#1: protons/isotopes). Give the number of protons, neutrons, and electrons in ^{60}_{27}Co^{2+} . nucleus. In fact, succeeding in coaxing a group of atoms to be very close to identical was worthy of a Nobel Prize. the Advancement of Science wrote in their Project 2061, "Science \[\text{atomic number} = \left( \text{number of protons} \right) = 19 \nonumber \]. As a result of the EUs General Data Protection Regulation (GDPR). The mass number is equal to: a. the sum of the number of electrons and protons. The site owner may have set restrictions that prevent you from accessing the site. Example. The atom with the same number of neutrons as 12C is: 1) 9Be. To state the case succinctly, it is very hard to have two atoms of the same element be exactly identical. and electrons. The sum of the number of protons and neutrons 49. b. electron c.) proton d.) neutron 4.) mass of 1.008 amu. Isotopes are atoms of the same element that: a. have different numbers of electrons. Isotopes (a) are atoms of different elements which have the same mass. will have different atomic masses. All atoms of the same element have the same number of _____ in their nucleus. What effects accomplishments did Francisco have. masses of 2.014 amu and 3.016 amu respectively. All atoms of an element have the same atomic number. c. the same number of electrons d. the same mass numbers.
