13 protons 14 neutrons 10 electrons. Learn with flashcards games and more for free. Aluminum has 13 protons and 13 or 14 neutrons. No jab in 2021 means no entry to anything yes.
Atomic mass is equal to number of protons number of neutrons. A neutral atom has the same number of protons and electrons charges cancel each other out. Silicon has 14 protons and 14 to 18 neutrons.
An aluminum isotope consists of 13 protons 13 electrons and 14 neutrons. Because aluminium is atom number 13 in the periodic system so it has 13 protons. 28 protons 14 neutrons 14 electrons 10 to find the neutrons do the mass number of the element minus the atomic number of the element.
However when an atom has an unequal number of protons and electron it has an electrical charge and they create ions. The isotope with 13 protons and 14 neutrons is aluminum 14. Neutrons are neutral particles.
If 10 of them have counter parting electrons then 3 positive proton charges are left uncompensated by. Protons and neutrons are called nucleons. Kvargli6h and 5 more users found this answer helpful.
2 get other questions on the subject. If an ion has more protons than electrons it is positively charged and is called a cation. The element of the isotope can be determined by either the number of electrons or protons which are equal to the atomic number of an element.
Atoms are electrically neutral because they possess an equal number of electrons and protons. An observation that requires measurement is called quantitative observable or qualitative. Conversely if an ion has more electrons than electrons it is negatively charged and is called an anion.
