The only element with three protons is lithium.The isotope lithium-6, has 3 neutrons and is the rarer of the two stable isotopes of lithium.Most lithium is isotope lithium-7, containing 3 protons, 3 electrons, and 4 neutrons. It makes up about 92.5 percent of the lithium found on Earth.
carbon dioxide has three atoms, one carbon with six protons and six neutrons, each oxygen has 8 protons and 8 neutrons. 6 + 8 + 8 = 22 protons
It's an isotope of Carbon, specifically Carbon-4. An atom in its neutral state will have equal numbers of protons and neutrons. The number of protons is also called the atomic number, and makes the specific atom what it is. (Carbon always has 6 protons, 5 protons is Boron and 7 protons is Nitrogen.) If there is an unequal number of neutrons, it usually indicates an isotope, an atom that isn't in the natural, most commonly occurring ground state. In this instance, it is Carbon-4. (Carbon-4, also called C-4 is a common explosive because of it's unstable nature.)
Nucleons are the particles that make up the nucleus of an atom. That means protons and neutrons. The number of nucleons here would be 12 because the 6 protons and 6 neutrons add up to 12 nucleons.
a regular boron atom (5B11 isotope) has six neutrons and five protons
Not sure about an 'Osotope' Isotope: A variation in the number of neutrons in the core of an atom of a given element is an isotope of that element. Carbon has six protons in the core of the atom. Carbon-12 has six neutrons in its core. Carbon-13 has seven neutrons. Carbon-13 is an isotope of Carbon.
One beryllium atom has four (4) electrons, four (4) protons, and three (3), five (5) or six (6) neutrons, depending on the isotope being considered. The only stable isotope is Beryllium-9 (with 5 neutrons) but beryllium-10 (with 6 neutrons) has a relatively long half-life of 1.51 million years.
An atom with with five protons, six neutrons, and five electrons
carbon has six protons and six neutrons
Nucleus of the standard isotope of carbon atom has 6 protons and 6 neutrons (carbon 12). Other Isotopes of carbon atoms are also possible, such as C14, which has 8 neutrons, and decays by beta particle emission into nitrogen.
Boron-10 has five protons and 5 neutrons Boron-11 is an atom that contains five protons and six neutrons
12 - 6 = 6 neutrons; the number of neutrons in an isotope is always the mass number minus the atomic number.
