Summaries the rule for writing of distribution of electrons in various shells for the first eighteen elements?

Posted by Tridev Prakash 3 years, 2 months ago

CBSE > Class 09 > Science

1 answers

Sia ? 3 years, 2 months ago

the following rules are followed for writing the number of electrons in different energy levels or shells.

(i) the maximum number of electrons presents in a shell is given by the formula 2n² where ′n′ is the orbit number of energy level index 1,2,3... hence the maximum number of electrons in different shells are as follows :
First orbit or K-shell will be = 2 × 1² × 2 Second orbit or L shell will be = 2 × 2² = 8 third orbit or M shell will be = 2 × 3² = 18 fourth orbits or N-Shell will be = 2 × 4² = 32 and so on.

(ii) The maximum number of electrons that can be accommodated in the outermost orbit is 8.

(iii) Electrons are not accommodated in a given shell unless the inner shells are filled. That is the shells are filled in a stepwise manner.

Posted by Harsh Kant Harsh 3 years, 2 months ago

CBSE > Class 09 > Science

2 answers

Sia ? 3 years, 2 months ago

Through combining two or more substances, a mixture is produced. A homogeneous solution tends to be identical, no matter how you sample it. Homogeneous mixtures are sources of water, saline solution, some alloys, and bitumen. Sand, oil and water, and chicken noodle soup are examples of heterogeneous mixtures.

Tanu Shri Saini 3 years, 2 months ago

HOMOGENEOUS - the mixture which has uniform composition.example - suger+water , alcohol+water etc. HETEROGENEOUS - the mixture which has non-uniform composition.example - sand+water, water+oil etc.

Sia ? 3 years, 2 months ago

Motion is always relative. Based on the energy of the particle under motion, the motions are classified into two types:

Bounded Motion
Unbounded Motion

In bounded motion, the particle has negative total energy (E<0) and has two or more extreme points where the total energy is always equal to the potential energy of the particle i.e the kinetic energy of the particle becomes zero.
