Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.

Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
What is the number of of electron shells in CALCIUM?

What do bromine and chlorine have in common?
The atoms of both elements have seven valence electrons and a strong tendency to abstract, from a less electronegative atom, an electron to complete their valence shells and thereby become an anion.
How many valence shells in radium?
Radium has seven electron shells; the valence of radium is 2+.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
What is the total of valence electrons of BrO31?
Every oxygen atom has -2 as its oxidation number (and 8 electrons in its valence shells). By balancing the charges, bromine is in +5 state: +6 with six bonds with oxygen and -1 from central charge. After counting the electron that is not involved above--bromine has 14 electrons in its valence shell.
Why are fluorine chlorine bromine and iodine placed in the same group?
Fluorine, chlorine bromine and iodine have seven electrons in their valence shells, and they all need one electron to have stabilized electron configuration. Therefore they are grouped in Group 17 (halogen group) of periodic table.
How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.
