What does it it mean to say that some elements are reactive and form ions easily whereas others do not?
Elements form ions by either gaining or losing valence electrons. The elements that lose electron(s) and gain electron(s) acquire a positive charge and negative charge respectively. The elements that lose and gain the least electrons require less ionization energy, and are more reactive than elements that need to lose or gain more electrons. For instance, elements in group 1 of the Periodic Table need to lose one electron, and are more reactive than elements in group 2 that need to lose 2 electrons.
Are there more elements or more non-elements?
All matter is made up of various elements, and most elements are found in the form of compounds. There are far more compounds than there are elements.
Are there more metalic elements or nonmetalic elements listed on the periodic table?
There are more metals than nonmetals on the periodic table. There are 18 nonmetals, compared to 117 known elements.
Are there more than 1000 known elements?
There are 118 known chemical elements as of 2011.
What kind of elements can form ions with more than one charge?
Transition elements are the major group of elements with this property.
Three elements that make more than 90 percent of your body?
water protein fat
What is the 12 elements that together account for 0.7 percent of the body weight with each accounting for no more than 0.02 percent?
trace elements
Is there more compound than elements?
There are more compounds than elements
Why is oxygen more important than the other elements?
Oxygen is what humans breathe in. We need it to be alive.
Elements with more than 92 protons are called?
Elements with more than 92 protons are called Transuranic elements.
Is there more compoundsor more elements?
There are far more compounds than elements: Fewer than 200 elements and many million distinct compounds.

Are most elements on the periodic table nonmetals?
No, more than three-fourths of the elements are metals. Love, Grahamcracker
Why do you only have 25 elements in your body?
According to the Wikipedia entry on Chemical makeup of the human body there are about 60 elements present, although some of them are not present to more than a few dozen micrograms. http://en.wikipedia.org/wiki/Chemical_makeup_of_the_human_body As to the question why there are not more, there is no definitive answer.
Do children need more energy than adults?
Adults need more energy in absolute terms, but children need more relative to their age and body weight.
What is is the function of pressure in the body?
Most pressure is need for the body. It is more important than oxygen, nutrients and organs.
