What is the atomic symbol for an atom with 82 protons and 125 neutrons include the symbol for the unknown element the mass number and the atomic number in your answer?
What is the atomic symbol for an atom with 82 protons and 125 neutrons include the symbol for the unknown element the mass number and the atomic number in your answer?
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 element has 80 protons and 124 neutrons?
Mercury – Hg
What is the number of protons in the nucleus of any other isotope of lead?
82
What is the sum of the protons and the neutrons in the nucleus of an isotope called?
mass number
How do you find protons in an isotope?
Understand that isotopes of an element have different mass numbers but the same number of protons. Using the Periodic Table, find the atomic number of the element. The atomic number equals the number of protons. In a balanced atom, the number of electrons equals the number of protons.
What is the atomic number of an isotope?
The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.
How many electrons are in the average human body?
Thus, in the average human body, there will be 50000 g/ 12 g = 4167 packets of 12 g of carbon each, i.e. 25002 x 10^23 atoms, or, expressed more conventionally, 2.5 x 10^27 atoms. Each of these has six electrons. I.e. the average human body contains about 1.5 x 10^28 electrons.
What is the importance of electrons to human life?
Electrons are also important for the bonding of individual atoms together. With out this bonding force between atoms matter would not be able to interact in the many reactions and forms we see every day.
What is the purpose of electrons?
Electrons are very important in the world of electronics. The very small particles can stream through wires and circuits, creating currents of electricity. The electrons move from negatively charged parts to positively charged ones.
