(a)
Interpretation:
The valence shell representation of a helium atom should be drawn.
Concept Introduction:
In a planetary model of an atom, negative charged electrons are arranged around the positive charged electron in a series of shells which is like orbits.
The electrons present in atoms are revolving around the nucleus with different energies is known as
The number of electrons that these subshells can hold is:
s-block - 2
p-block - 6
d-block - 10
f-block - 14
The electrons present in the outermost energy level or shell is known as valence electrons. These electrons are available for bonding and outermost shell is known as valence shell.
(b)
Interpretation:
The valence shell representation of a sulphur atom should be drawn.
Concept Introduction:
In a planetary model of an atom, negative charged electrons are arranged around the positive charged electron in a series of shells which is like orbits.
The electrons present in atoms are revolving around the nucleus with different energies is known as Bohr Model. Electrons are distributed in the orbitals of the subshell. The specific region of space in which the movement of electrons is confined is said to be shells which are divided into subshells and are s-, p-, d-, and f-. Among these subshells, the electrons are grouped as orbitals.
The number of electrons that these subshells can hold is:
s-block - 2
p-block - 6
d-block - 10
f-block - 14
The electrons present in the outermost energy level or shell is known as valence electrons. These electrons are available for bonding and outermost shell is known as valence shell.
