use the periodic table to identify an element is by looking for the element's name or elemental symbol.
Answer:
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

hope it's right
White matter is made of axons connecting different parts of grey matter to each other
We know that E = 0.5mv^2 = hc/(lambda), where lambda is the de broglie wavelength. E = 0.5mv^2 due to the speed that the alpha particle possess in the form of kinetic energy. Hope this helps!
Answer:
12: This is decomposition because nitrogen triiodide is breaking apart.
13: This is double displacement because the elements in the compounds are "switching".
14: This is synthesis because the water and carbon dioxide are combining.
15: This is also synthesis because the hydrogen and oxygen are combining.
16: This is single displacement because the sodium is "switching" the element it's bonding with.
