How do you prolong a sentence?
A sentence can be extended with a semicolon when a slight break is preferable to a new sentence. For example: No one was hurt in the accident; the only real injury was a broken finger.
Is an atom smaller than a molecule?
Atoms are smaller than molecules, and they are also the smallest building blocks of matter. Atoms make up molecules when two or more atoms bond…
What are the new set of compounds?
When atoms of different kinds combine to form a compound, a new substance is created. New compounds do not have the same physical or chemical traits of the original elements. They have a new life of their own. Compounds are written with formulas showing which elements from the periodic table are combined.
Are atoms mostly empty space?
Atoms are not mostly empty space because there is no such thing as purely empty space. Rather, space is filled with a wide variety of particles and fields. Even if we ignore every kind of field and particle except electrons, protons and neutrons, we find that atoms are still not empty. Atoms are filled with electrons.
What is the largest molecule ever found?
In 1995 biologists smashed records by cloning the DNA for the largest protein molecule known. The aptly named titin weighs in at a molecular weight of 3 million and consists of a continuous chain of 27,000 amino acids, making it 20 to 50 times larger than the average-size protein.
What is the smallest unit of a compound?
Which molecule is the smallest?
Can salt and water make a compound?
For example, sodium chloride (salt) and water are both compounds. They mix together when salt dissolves in water to form salt solution. It is much, much more difficult to un-combine the elements that make up compounds.
What is the smallest unbreakable unit of a compound?
Do we ever really touch anything?
Particles are, by their very nature, attracted to particles with an opposite charge, and they repel other similarly charged particles. This prevents electrons from ever coming in direct contact (in an atomic sense and literal sense). Their wave packets, on the other hand, can overlap, but never touch.
