Because there is less of it available.
The answer is: Cl2.
Chlorine is diatomic molecule made of two chlorine atoms.
Diatomic molecules are molecules made of two atoms.
They can be homonuclear (molecule made of two atoms of the same element) and heteronuclear (molecule made of two different atoms).
Chlorine (Cl) is halogen element.
Halogen elements are in group 17: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). They are very reactive and easily form many compounds.
<u>Answer:</u>
70 kilometers per hour
<u>Explanation:</u>
280 kilometers ÷ 4 hours (7:00 pm - 3:00 pm = 4 hours) = 70 kilometers per hour

<span>The first ionization
energy is the energy that is obligatory in order to eliminate the first
electron from an atom(neutral) in the GAS phase
, the second ionization energy is defined as the
energy required to remove the second electron from an atom(+1 ion) in the GAS phase.
</span>the third ionization energy is the energy it takes to remove an electron from a 2+ ion. (That means that the atom has already lost two electrons, you are now removing the third.)
<span> Ionization energy will normally increase for every electron that is removed and
increases from left to right in the periodic table and moving up the periods

Answer: m Most likely Group2 metals and Group 17 non-ktta
Explanation:
A little more information is needed to be certain, but the likely answer is that X belongs to Group 2 and Y belongs to Group 17. Group 2 metals (Be, Mg, Ca, Sr, Ba, etc.) are all divalent. They gave rive up 2 electrons each to return to a full shell. Group 17 elements (e,g, F, Cl, Br, I, etc.) all require 1 electron to reach a full valence shell. That would make the proportion 1X to 2Y, or XY2. It is possible that a metal outside of Group 2 would also have a valency of 2. Iron(II) forms FeCl2, for example.
