Without the specific diagram of the atom you are referring to, I can provide general true statements about atomic structure based on standard atomic models:
- The atom consists of a nucleus containing protons (positively charged) and neutrons (neutral), with electrons (negatively charged) orbiting the nucleus in shells or energy levels
- The number of protons in the nucleus equals the atomic number of the element and also equals the number of electrons in a neutral atom, resulting in no overall electrical charge
- Electrons fill the lowest energy shell first, with the first shell holding up to 2 electrons, the second up to 8, and the third also up to 8 electrons in simpler models
- The electronic structure of an atom can be written as a list of numbers indicating the number of electrons in each shell, for example, sodium’s electronic structure is 2, 8, 1
- The mass number of an atom is the sum of protons and neutrons in the nucleus, and the number of neutrons can be calculated by subtracting the atomic number from the mass number
Therefore, a true statement about an atom shown in a typical atomic diagram would be one that correctly identifies:
- The nucleus contains protons and neutrons.
- Electrons orbit the nucleus in shells.
- The number of protons equals the number of electrons in a neutral atom.
- The electronic structure follows the filling order of shells starting from the innermost.
If you provide the specific diagram or details of the atom shown, I can identify the exact true statement related to that atom.
