Are two atoms of the same element identical?

Nitin Mereddy 15th Nov, 2021

. Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are different. The excited copper atom will emit a bit of light when the electron relaxes back down to the ground state, and the copper atom already in the ground state will not. Since the states of the electrons in an atom are what determine the nature of the chemical bonding that the atom experiences, two atoms of the same element can react differently if they are in different states. For instance, a neutral sodium atom (say, from a chunk of sodium metal) reacts with water much more violently than an ionized sodium atom (say, from a bit of salt). Chemists know this very well. It's not enough to say what atoms are involved if you want to fully describe and predict a reaction. You have to also specify the ionization/excitation states of the electrons in the atoms.

The Aicte has regarded maths physics and chemistry as optional subjects for admission in engeeneering. So, can Cec students write Ts EAMCET 2022 and get admission?

Sharon Rose Student Expert 27th Dec, 2021

Hello,

As per AICTE new norms for admission to B.Tech a candidate must score minimum 45% in any three subjects from the following

  • Physics
  • Mathematics
  • Chemistry
  • Computer Science
  • Electronics
  • Information Technology
  • Biology
  • Informatics Practices
  • Biotechnology
  • Technical Vocational subject
  • Engineering Graphics
  • Business Studies and Entrepreneurship

It is also stated that the institute or University can issue its guidelines which means that AICTE has left the decision to the institutes/University to determine the eligibility criteria for admission to Engineering. As of now the eligibility criteria to appear for TS EAMCET 2022 for admission to Engineering course is that you must have passed 10+2 or its equivalent with Mathematics, Physics and Chemistry as optional or related vocational courses in the fields of Engineering and Technology with minimum 45% of marks in case the candidate belongs to general category and minimum 40% of marks in case the candidate belongs to reserved category in the subjects specified taken together in 10+2 level. Considering the eligibility criteria you are not eligible to apply for TS EAMCET 2022.

is there Aeee entrance exam for integrated MSc chemistry or physics to Amrita University Amrita puri

dhanshree1501 2nd Dec, 2021

Hello Aspirant,


Amrita Vishwa Vidyapeetham (Deemed to be University) conducts the Amrita Entrance Examination Engineering (AEEE) for admission into the undergraduate engineering programmes offered by the University. The authorities conduct the AEEE 2022 as both a computer-based test as well as pen and paper test.


I do not think there is any entrance exam for any MSc programmes in the university.

Please look into other options.

All the best!

I am currently enrolled in bsc Hons chemistry in du. Can i do bsc hons biochemistry from Ignou distance) simultaneously in 2021? Will it be valid or legal??

Rituparna Priyadarshini 23rd Dec, 2021

Hello.

As you know it is not l gal to get bachelor's degree from two different institutions at the same time. Some people do enroll themselves into both the courses, but you cannot show anywhere that you have completed both the course simulataneously. Hence, it is not legal to carry on with both the courses from two different universities at the same time.
