ইংরেজীএ MOLECULE এর মানে কি?
অণু
একটি অণু / mɒlɪkjuːl / হল একটি ইলেকট্রনিকভাবে নিরপেক্ষ গ্রুপ যা রাসায়নিক বন্ধন দ্বারা একত্রে গঠিত দুটি বা তার বেশি পরমাণু। বৈদ্যুতিক চার্জের অভাবে অণুগুলি আয়ন থেকে পৃথক। যাইহোক, কোয়ান্টাম পদার্থবিজ্ঞানে, জৈব রসায়ন এবং জৈব রসায়ন, শব্দ অণুটি প্রায়ই কঠোরভাবে ব্যবহৃত হয়, এছাড়াও বহুমাত্রিক আয়ন প্রয়োগ করা হচ্ছে। গ্যাসের গতিবিজ্ঞান তত্ত্বের মধ্যে, শব্দটির অণুটি সাধারণত কোনও গ্যাসীয় কণাের জন্য ব্যবহৃত হয়, যদিও এর গঠনটি নির্বিশেষে। এই সংজ্ঞা অনুযায়ী, একক অ বন্ধনী পরমাণু গঠিত হওয়ার পরও উত্তম গ্যাস পরমাণুর অণুগুলি বিবেচনা করা হয়। একটি অণু homonuclear হতে পারে, যে, এটি একটি রাসায়নিক পদার্থ পরমাণু গঠিত, অক্সিজেন হিসাবে হিসাবে; অথবা এটি একটি রাসায়নিক পদার্থ হতে পারে যা একাধিক উপাদান দ্বারা গঠিত, যেমন জল। অ-সমান্তরাল বন্ড যেমন হাইড্রোজেন বন্ড বা ionic বন্ড দ্বারা সংযুক্ত পরমাণু এবং জটিলগুলি সাধারণত একক অণু হিসাবে বিবেচিত হয় না। বস্তুর উপাদান হিসাবে অণু জৈব পদার্থ মধ্যে সাধারণ। তারা মহাসাগরের অধিকাংশ এবং বায়ুমণ্ডলও তৈরি করে।
ইংরেজীএর অভিধানে molecule এর সংজ্ঞা
অভিধানে অণুটির সংজ্ঞাটি রাসায়নিক যৌগের সর্বনিম্ন একক, যা বিদ্যমান থাকতে পারে, যা রাসায়নিক বন্ধন দ্বারা একত্রে দুটি বা ততোধিক পরমাণু গঠিত। অণুর অন্য সংজ্ঞাটি খুবই ছোট কণা।
«MOLECULE» নিয়ে ইংরেজী এর উদ্ধৃতি
molecule শব্দটি আছে এমন বিখ্যাত উদ্ধৃতি ও বাক্যসমূহ
As is known, the sugar molecule as it passes through lactic acid can easily be split by purely chemical means.
It now seems certain that the amino acid sequence of any protein is determined by the sequence of bases in some region of a particular nucleic acid molecule.
The body itself is an information processor. Memory resides not just in brains but in every cell. No wonder genetics bloomed along with information theory. DNA is the quintessential information molecule, the most advanced message processor at the cellular level - an alphabet and a code, 6 billion bits to form a human being.
Calling on each molecule one by one? No way. I just told all of them to be quiet - except for a selected few.
The detailed geometry of the coenzyme molecule as a whole is fascinating in its complexity.
The more the relationships of the nitrogen-rich substances to the cell nucleus were recognized, the more the question of the arrangement of the nitrogen and carbon atoms in the molecule came to stand out.
We may say that a basic substance is one which has a lone pair of electrons which may be used to complete the stable group of another atom, and that an acid is one which can employ a lone pair from another molecule in completing the stable group of one of its own atoms.
Nanotechnology is the idea that we can create devices and machines all the way down to the nanometer scale, which is a billionth of a meter, about half the width of a human DNA molecule.
Carbon nanotubes are amazing because they're really good electrical conductors, yet they are only a few atoms in diameter. You can make transistors out of them in the same way you can with silicon. At Berkeley, we made the narrowest device anybody had ever made. It was basically a single molecule.
The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.
