Answer:
Electron groups could be considered as Lone pair electrons and bonded pairs of electrons.
Answer: Option D & B
Explanation:
The two or more electrons can be bonded by single bond, double bond, covalent bond of electrons can simply be lone pair of electrons. Unshared pair of electrons are generally termed as lone pair of electrons in an atom which are generally present in the outermost shell of atoms. Hence electron groups can be determined by bonded pairs and lone pairs of electrons.
I got this from another brainly user
Answer:
(a)
(b)
(c)
(d)
Explanation:
Given:
Kinetic Energy of an electron,
radius of the orbit,
we have:
mass of an electron,
charge on an electron,
(a)
we know:
(b)
<em>We also have the relation after the comparison of forces(centripetal and magnetic) on a moving charge in a magnetic field as:</em>
...........................(1)
where:
B = magnetic field normal to the plane of circulating charge
putting respective values in eq. (1)
(d)
angular speed:
∴Time taken for 1 radian:
Now time take for 1 circulation i.e. 2π radians(Time period):
(c)
we know frequency :
