Answer:
The characteristic of silicon that is most closely related to its chemical reactivity is that;
It is found in nature in mainly as oxides and silicates
Explanation:
Silicon, which is a member of group 14 of the periodic table has the electron configuration of [Ne]3s²3p² and has a high affinity for oxygen such that the the oxides are known as silicates and it is almost impossible to find pure silicon in nature and it is found in the universe as silica and silicates
Silicate minerals make up over 90% of the Earth's crust such that, by mass silicon is only surpassed by oxygen as the most abundant element found in the Earth's crust.
Answer:
Explanation:
When looking at a chemical reaction, the substance present before the reaction takes place are called the (5)
REACTANT
and the substance produced after the reaction are the (6).
PRODUCT
know through the Law of Conservation of (7)
MATTER
that nothing is created or destroyed. This is reflected in a (8
BALANCED
chemical equation, where the NUMBER OF atoms of each element on each side of the arrow is (9)-
equal
or the same.
REMEMBER: WHEN BALANCING EQUATIONS YOU CANNOT CHANGE THE SUBSCRIPTS OF THE COMPOUNDS, YOU CAN ONLY SHOW BY THE COEFFICIENTS HOW MANY MOLECULES YOU HAVE!
Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles. Therefore, he proposed a model of the atom which he likened to plum pudding. ... Rutherford with the assistance of Ernest Marsden and Hans Geiger performed a series of experiments using alpha particles.
