because some atoms are bigger than others
No, the words 'later' and 'discovered' are not nouns.The word 'later' is the comparative form of the adjectiveand adverb 'late' (later, latest).The word 'discovered' is the past participle, past tense of the verb to discover. The past participle of the verb also functions as an adjective.Examples:We can take the later train. (adjective)She arrived later than usual. (adverb)I discovered a great little shoe store. (verb)His newly discovered hobby is absorbing all of his time. (adjective)
See also the "Related Questions" link to the left of this answer: "Why are elements arranged as they are in the periodic table?" Once you've looked at the question above, read this: The gaps are due to the fact that the different electron orbitals (s, p, d, f) hold different numbers of electrons each. An s-orbital can hold at most 2 electrons, while a p-orbital can hold up to 6, a d-orbital can hold up to 10, and an f-orbital can hold as many as 14 electrons. In order to align the columns of the periodic table so that each element in the column has the same outermost (or valence) electron configuration, there need to be gaps. Actually, if you look at the modern periodic table, there is always a block of elements separate from the others (called the Lanthanides and Actinides, or the f-block elements) at the bottom. You can actually draw the periodic table with even bigger gaps is if you include those together with the rest of the elements. Drawing it this way is cumbersome because it is so long and narrow, but it is actually a better way to see the trends in the electron configurations. See the Web Links to the left for periodic tables that show the electron configurations of each element, as well as this funny looking stretched out version with the f-block elements all in the same table.mendeleevs left the gaps for the elements that's hadnt been dicovered by then but he pridicted that more element can be discovered in the future and placed them according to their properties after a specific period.Some elements pridicted by mendeleevs were eka aluminum which we today call galium.Eka means an element with similar properties to that of aluminum and galium does have properties similar to aluminum.
There are currently over a thousand known planets, most of them discovered recently; I would guess that currently, dozens of planets, perhaps over a hundred planets, are discovered every year.
HCFC is the latest ozone friendly product. It succeeds CFC's.
The latest exploration on Mars is going on currently. They are looking for new ways to solve every day problems such as cancer.
The latest confirmed element discovered was Livermorium, 116Lv, in 2000. Ununseptium is not officially credited as "discovered" by the IUPAC/IUPAP Joint Working Party, but it is the most recently synthesized element, made in 2010.
New planets are discovered every few days.
Ununseptium, discovered in 2010

That SHANE DAWSON IS AWESOME!
That is right. The latest edition that I have gives 108 elements.
Ununseptium, Uus Ununoctium, Uuo
China, because they got the rare earth elements.
The latest discovered exoplanet(that is outside our solar system) is Kepler-20f. It has approximately the size of Earth and it's in the goldilocks zone of it's star. Exoplanets are being discovered too quickly right now for "latest" to have meaning for longer than a couple of days... a week at most. It's still December 2011, and 20f is no longer the latest discovery.
um... pretty sure no-one's 'discovered' any robots, but if you mean the people who first saw them, then I guess that'd be the inventor of the robot? And the answer to THAT question would probably be someone in Japan. No racism intended. :)
Ununtrium, Uut Ununquadium, Uuq Ununpentium, Uup Ununhexium, Uuh Ununseptium, Uus Ununoctium, Uuo
Plastic is the cheap component in two wheelers. Plastic is flexible and lighter, making the two wheeler more durable.
