Magnesium. You can count the electrons in each level and because the number of electrons is the same with protons you have the atomic number based of which you can get the element in the periodic table
Answer:
Japan, China, the U.S., Indonesia, Chinese Taipei and South Korea have been named by Pew Charitable Trusts on a “shame list” of countries responsible for overfishing tuna in the Pacific. According to Pew, the “Pacific 6” are responsible for 80 percent — 111,482 metric tons in 2011 — of the annual catch of bigeye tuna.
Hope it will help you
Answer:
Explained below
Explanation:
Metalloids are elements that possess properties between that of metals and non - metals or that have properties that a re a combination of those of metals and non - metals. Whereas a metal is one that conducts electricity and heat very well.
Now, the property they both share is that they both possess valence orbitals which are highly de-localized over macroscopic volumes, thereby allowing both of them to be conductors of electricity although it has to be said that Metalloids don't conduct electricity as much as metals.
As the period number increases on the periodic table, moving from top to bottom, the atomic radius of the elements increases as well.
It has a trigonal planar structure. So, the calculated angle is 127.3 degrees.
You can see the structure in the picture.
