Each12C atom has six protons and six neutrons in its nucleus, adding up to an atomic mass of 12 AMU.Electronshave a low mass, so they are assumed to have a negligible effect. Consequently, the nucleus accounts for almost the entire mass of the atom of any element, which means that a ...
In all atoms, the number of protons and the number of electrons is always the same. So nitrogen has 7 protons and 7 electrons, calcium has 20 protons and 20 electrons, and tin has 50 protons and 50 electrons. The number of neutrons is very roughly the same as the number of protons, ...
What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons? All the isotopes of a given atom have what? The core of an atom contains protons and How many protons are in the nucleus? What part of an atom has a negative charge and is found outside of the ...
What is the smallest part of the atom that has almost no weight? What element has the most stable isotopes? What element has 53 protons and 74 neutrons? What element has 4 protons 5 neutrons and 2 electrons? What element has 6 protons, 8 neutrons, and six electrons?
Answer and Explanation: An atom that has more protons than electrons is called a cation. Ions are charged atoms or combinations of atoms. When an atom loses one or more... Learn more about this topic: Cation | Definition, Formation & Examples ...

What element has a ground state electron configuration that contains five unpaired 5d electrons? An element in its ground state has the following electron configuration: (Ne)3s23p2. What is this element? An elemen...
The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6. Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 ne...
