HELP true or false: if all the bonds in a molecule are polar the molecule is a polar molecule

Chemistry

The given statement is False.
Not all molecules having polar bonds are polar. An example is linear carbon dioxide molecule (CO 2). The individual C−O bonds are polar but the molecule on the whole is non polar as individual bond dipoles cancel each other. Another example is boron trifluoride (BF 3) molecule with triangular planar geometry. Another example is carbon tetrachloride (CCl4) with tetrahedral geometry.

Nope. A polar molecule is where the charges are unevenly distributed so the electron negativity values are greater than 0.5. A molecule can have polar bonds but distributed evenly so they cancel out

Yes, because a mixture is 2 or more substances that are mixed together (not chemically). A mixture could be two different elements physically combined in a set ratio.

Why does it matter if atoms are divisible ???
Andreyy89

Atoms are divisible contrary to the early beliefs that the smallest "indivisible" matter is an atom. When an atom loses its identity it means that they are divisible. Atoms chemically react with other kinds of atoms thus changing their activity.

They certainly are not that important to our lives, but it’s good to know :)

The last element in any period always has:
brilliants [131]

Answer: The correct option is The properties of a noble gas.

Explanation: There are 7 periods in the periodic table.

The last element of each period are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn) and Ununoctium (Uuo).

  • The electronic configuration for Helium is 1s^2. For He, The outermost electrons are 2.
  • The electronic configuration for all the other elements is ns^2ns^6 ( where, n = 2, 3, 4, 5, 6 and 7 respectively). For all the other gases, the outermost electrons are 8.

All these elements have stable electronic configuration and are not reactive in nature. Hence, they are considered as noble gases.

Therefore, the last element of each period always have the properties of a noble gas.
