How can there be more than 1000 different atoms when there are only about 100 different elements?

Actually, there are only about 100 atoms that have been yet discovered. But each element has many different kinds of atom. For instance, carbon. Do you know carbon has more than 30 or 50 different types of atoms? Well, how? There are isotopes. Don't think that there is only one carbon atom which has 6 electrons and 6 protons and 6 neutrons. There are more. C-13 has 6 electrons and 6 protons and 7 neutrons. While, C-14 has 6 electrons and 6 protons and 8 neutrons. I just showed you three stable isotopes of carbon(element). But, what is really an isotope?? Did you notice that all of these atoms had the same number of protons and electron but different numbers of neutrons? This is really an isotope. Well, if an atom takes a few more electrons or gives off a few electrons, it still stays the same element/ atom type. Just like that an element can have atoms of different neutron number. It may be less or more. It doesn't affect the atom much: just makes an isotope. But it does affect the atomic mass number or radioactivity of an atom. So, an element can have many different forms of isotopes of its atoms. In this way, being only 100 atoms, there can 1000 atoms or (more than that!). 

To make it more clear-

Definition of ISOTOPE: <span>any of two or more forms of a </span>chemical<span> element, having the same number of protons and electrons in the nucleus, or the same atomic number, but having different numbers of neutrons</span>

HOPE YOU UNDERSTOOD THE MATTER:-))

There can be more atoms because atoms make about everything and those atoms make up the elements and since,atoms are in everything there can be different kinds of atoms to make up certain things.

Which combination of reagents used in the indicated order with benzene will give m-nitropropylbenzene? a. 1) CH3CH2CH2Cl/AlCl3,
VladimirAG [237]

Answer:

1) HNO3/H2SO4, 2) CH3CH2CH2Cl/AlCl3

Explanation:

Benzene is a stable aromatic compound hence it undergoes substitution rather than addition reaction.

When benzene undergoes substitution reaction, the substituent introduced into the ring determines the position of the incoming electrophile.

If I want to synthesize m-nitropropylbenzene, I will first carry out the nitration of benzene using HNO3/H2SO4 since the -nitro group is a meta director. This is now followed by Friedel Craft's alkykation using CH3CH2CH2Cl/AlCl3.

How many significant figures does the following number contain: 385.01
dusya [7]

Answer:

5 significant figures

Explanation:

  • Zeros that come before any non-zero digits are never significant.

  • Zeros that are in between any non-zero digits are always significant.

  • Zeros that come after any non-zero digit are ONLY significant if a decimal point in present somewhere in the number. (In this case there is a decimal point, but there aren't any zeros at the end of this number.)

I have underlined the significant figures in this number:

<u>3</u> <u>8</u> <u>5</u> . <u>0</u> <u>1</u>

Why did all sodium compounds show the same colour in the flame
Alinara [238K]
All sodium compounds show the same coloured flame because sodium’s familiar bright orange-yellow flame colour results from promoted electrons falling back from the 3p1 level to their normal 3s1 level. The exact sizes of the possible jumps in energy terms vary from one metal to another.

Why don’t the common ions in humans (na+, k+, cl-, etc.) cluster together in cells?
mariarad [96]
The answer is because like electric charges do not attract with each other. Ions either lack or have excess electrons in their atomic structure. Ions with a positive charge are called cations. They lack electrons in their atoms so they have to pair up with negatively charged ions, called anions, because they have excess electrons. Together, they form a compound that is neutral.
