If we have a sample of slicon (Si) atoms that has 14 protons, 14 electrons, and 18 neutrons What is the name of this specific slicon isotope? silicon -14 slicon-32 silicon-46 silicon-153

The question is asking for the name of a specific isotope of silicon. Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom. The number of protons in the nucleus is called the atomic number, and the sum of the protons and neutrons is called the mass number. In this case, the silicon isotope has 14 protons and 18 neutrons, making the mass number 32 (14 protons + 18 neutrons). Therefore, the name of this specific silicon isotope is silicon-32.
