What can be stated for a particular element if only the group number of 14 is known?
If only the group number of 14 is known, it can be stated that the element belongs to Group 14 of the periodic table. Group 14 is also known as the Carbon Group, and it consists of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).
How many protons and neutrons and electrons are there
The number of protons, neutrons, and electrons in an element is determined by its atomic number and atomic mass.
For Group 14 elements:
- Carbon (C): Atomic number = 6, so it has 6 protons and typically 6 electrons (in a neutral atom). Atomic mass varies between isotopes, but a commonly occurring isotope, carbon-12 (C-12), has 6 neutrons.
- Silicon (Si): Atomic number = 14, so it has 14 protons and typically 14 electrons (in a neutral atom). Atomic mass varies between isotopes, but a commonly occurring isotope, silicon-28 (Si-28), has 14 neutrons.
- Germanium (Ge): Atomic number = 32, so it has 32 protons and typically 32 electrons (in a neutral atom). Atomic mass varies between isotopes, but a commonly occurring isotope, germanium-74 (Ge-74), has 42 neutrons.
- Tin (Sn): Atomic number = 50, so it has 50 protons and typically 50 electrons (in a neutral atom). Atomic mass varies between isotopes, but a commonly occurring isotope, tin-119 (Sn-119), has 69 neutrons.
- Lead (Pb): Atomic number = 82, so it has 82 protons and typically 82 electrons (in a neutral atom). Atomic mass varies between isotopes, but a commonly occurring isotope, lead-208 (Pb-208), has 126 neutrons.
- Flerovium (Fl): Atomic number = 114, so it has 114 protons and typically 114 electrons (in a neutral atom). The atomic mass of the most stable isotope, flerovium-289 (Fl-289), is uncertain, but it is expected to have around 175 neutrons.
It's important to note that while the number of protons defines an element and its identity, the number of neutrons can vary in different isotopes.
