The element with 4 valence electrons in the 6th shell is lead (Pb). Lead has 4 electrons in its outermost shell, which is the 6th electron shell.
The principal quantum number for valence electrons in lead is 6, because lead has 6 valence electrons in the 6th energy level.
Lead has 4 valence electrons.
There are 4 valence electrons in lead.
There are 4 valence electrons in lead.
Pb with 4 dots around it to represent its 4 valence electrons.
It is not possible to say for certain which pair of the isotopes below are of the same element as no options have been provided. There are many different pairs of isotopes that make up many different elements.
82. Lead is an element with symbol Pb and atomic number 82. The atomic number relates to the amount of electrons of the element
Lead has 4 valence electrons. You figure this out by first creating an Electron Configuration chart, and then adding up the last two S and P values (the ones furthest form the nucleus). There are 2 Ss and 2 Ps. 2+2=4!
You can tell if an atom has the same valence as carbon by looking at its outermost electron configuration. Carbon has 4 valence electrons, so any atom with 4 electrons in its outer shell, like silicon, would have the same valence as carbon.
The element with 82 protons is lead (Pb). The number of electrons in a neutral atom of lead is equal to the number of protons, which is 82. To find the number of neutrons, you subtract the number of protons from the mass number, which is 125 neutrons for this isotope of lead.
What has three energy levels and six valence electrons
