The atomic number of sulfur is 16.
What is the name of the elements with 82 protons?
On the periodic table of elements, lead is represented by the symbol Pb. It has an atomic number of 82 because it has 82 protons in its nucleus.
What element has a mass number of 82?
lead
The mass number of this isotope will be 82+125=207 units, while it has 82 protons. Looking on the periodic table, element number 82 is lead, and its symbol is Pb .
What is the charge of an atom with 16 protons and 18 electrons?
2–
Because the ion has 16 protons and 18 electrons, its net charge is 2–. Thus, the symbol for the ion is 32S2–.
What has 82 protons and electrons?
The atomic number of lead is 82, which means this ion contains 82 protons. Since it has a charge of +2 , this ion must contain 80 electrons.
What has 16 protons and 18 electrons and 18 neutrons?
The atomic number of sulfur is 16. The ion has 18 electrons that mean sulfur carries the charge of -2.
What has an atomic number of 82?
Lead
Lead has atomic symbol Pb and atomic number 82. It is located towards the bottom of the periodic table, and is the heaviest element of the carbon (C) family. The chemical symbol for lead is an abbreviation from the Latin word plumbum, the same root word as plumbing, plumber and plumb-bob still commonly used today.
What are the atomic number mass number and symbol for the element that has 82 protons and 126 neutrons?
A The element with 82 protons (atomic number of 82) is lead: Pb. B For the first isotope, A = 82 protons + 124 neutrons = 206. Similarly, A = 82 + 125 = 207 and A = 82 + 126 = 208 for the second and third isotopes, respectively.
What isotope has 82 protons and 125 neutrons?
The mass number is 207. So, the symbol of the isotope can be written as 20782Pb.
Which element contains 84 protons?
Polonium, (element 84), was discovered in 1898 and named after Poland, the homeland of Marie Curie (Ne Sklodowska) who found it with her husband Pierre Curie.
Which of the following elements has 18 neutrons?
chlorine
Some atoms of chlorine have 18 neutrons in their nuclei.
What element has 82 protons and 124 neutrons?
A The element with 82 protons (atomic number of 82) is lead: Pb. B For the first isotope, A = 82 protons + 124 neutrons = 206. Similarly, A = 82 + 125 = 207 and A = 82 + 126 = 208 for the second and third isotopes, respectively.
How many protons neutrons and electrons does the 79 SE 2 Ion possess?
protons, 26 neutrons, and 19 electrons; (b) the ion of sulfur that has 16 neutrons and 18 electrons. How many protons, neutrons, and electrons does the . 79. Se. 2– ion possess? Answer: 34 protons, 45 neutrons, and 36 electrons. Practice Exercise. Solution (a) The number of protons (22) is the atomic number of the element.
How many protons neutrons and electrons does oxygen 18 have?
Therefore, oxygen 18 has 10 neutrons. The number of electrons is a bit more complex, as the electrons are only loosely bound to the atom in a ‘cloud’. There are two main forces at play. An individual atom will want to have the same number of electrons as protons to balance out the charge.
What is the number of protons and electrons in gold?
Iridium has 77 protons, 115 neutrons and 77 electrons: 78: Platinum has 78 protons, 117 neutrons and 78 electrons: 79: Gold has 79 protons, 118 neutrons and 79 electrons: 80: Mercury has 80 protons, 121 neutrons and 80 electrons: 81: Thallium has 81 protons, 123 neutrons and 81 electrons: 82: Lead has 82 protons, 125 neutrons and 82 electrons: 83
