What element has 82 protons in the nucleus?
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 is the name of the element with 82 protons and 80 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 is the name symbol and charge of an ion that contains 15 protons and 18 electrons?
What is the symbol for an ion having 15 protons and 18 electrons? By referring to a periodic table or table of elements, we see that phosphorus (symbol P) has an atomic number of 15. Thus, each atom has 15 protons. The mass number of the ion is 15 + 16 = 31.
How many protons does an ion with 22 electrons and a charge of +2 contain?
overall charge of –2 for the anion side). The cation can now be represented as X2+, containing 20 electrons. Therefore, 22 protons must be present to give a charge of +2 (+22p – 20e = +2). The element with 22 protons is titanium.
What element has 82 electrons in its nucleus?
Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82.
What is the atomic symbol for an atom with 82 protons and 125 neutrons?
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 isotope symbol for atoms that contain 82 protons and 125 neutrons?
The isotope of an element X is given by AZX , where Z is the proton number of the element and A is the mass number of the element. 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 .
Which is the atomic number of an atom that forms an ion with 18 electrons and A charge of 2+?
Explanation: A certain element forms an ion with 18 electrons and a charge of +2. Recall that atoms have the same number of electrons as protons, and the atomic number of an atom is the number of protons it has. So, the atom in question is the atom whose atomic number is 20…..that’s calcium (Ca).
How many protons does krypton have?
36Krypton / Atomic number
What is the symbol of the element with the atomic number 82?
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.
