The particle with a -3 charge and 36 electrons is an ion of the element phosphorus (P). It has gained three extra electrons, resulting in a charge of -3.
The ion with 52 protons, 76 neutrons, and 54 electrons is the ion of element tellurium (Te) with a charge of +2. The number of protons determines the element, the number of neutrons can vary in isotopes, and the number of electrons determines the charge of the ion.
The element with 34 electrons is selenium. It has an atomic number of 34, which corresponds to the number of electrons in a neutral selenium atom.
Look at the periodic table. You see that the element that has 16 protons is Sulfur. Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-. So, the symbol of the ion would be S2- .
Since the anion has a 2- charge, it must have two more electrons than protons. The number of protons is 18 - 2, which is 16. Since the element has 16 protons, it is element 16, which is sulfur (S).
The charge of an ion is determined by the difference between the number of protons and electrons. In this case, the ion has 34 protons and 36 electrons, resulting in a net charge of 2- since there are 2 more electrons than protons.
Element 34, which is selenium, contains 2 protons less than krypton. Krypton has 36 protons, while selenium has 34 protons.
The particle with a -3 charge and 36 electrons is an ion of the element phosphorus (P). It has gained three extra electrons, resulting in a charge of -3.
The ion with 52 protons, 76 neutrons, and 54 electrons is the ion of element tellurium (Te) with a charge of +2. The number of protons determines the element, the number of neutrons can vary in isotopes, and the number of electrons determines the charge of the ion.
The element with 34 electrons is selenium. It has an atomic number of 34, which corresponds to the number of electrons in a neutral selenium atom.
No neutral element has these characteristics. However, the oxide ion, O-2, does have them.
Look at the periodic table. You see that the element that has 16 protons is Sulfur. Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-. So, the symbol of the ion would be S2- .
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
The element with 2 electrons and 7 protons is nitrogen. It has an atomic number of 7, which corresponds to the number of protons in its nucleus. The number of electrons in a neutral atom is equal to the number of protons.
Since the anion has a 2- charge, it must have two more electrons than protons. The number of protons is 18 - 2, which is 16. Since the element has 16 protons, it is element 16, which is sulfur (S).
The ion with 50 protons and 48 electrons is the element tin (Sn) with a charge of +2. This means it has lost two electrons to become positively charged.
Ion Sr2+ has 38 protons and 36 electrons. The number of protons remains the same as the atomic number of the element (38). The ion has a 2+ charge, indicating a loss of 2 electrons from the neutral Sr atom.
