Which atom or ion is the largest?<br><br> A. K<br> B. K+<br> C. Ca<br> D. Ca2+<br> E. Li
pishuonlain [190]

Answer:

A. K

Step-by-step explanation:

Remember the trends in the Periodic Table:

  • Atomic radii <em>decrease</em> from left to right across a Period.
  • Atomic radii <em>increase</em> from top to bottom in a Group.
  • Ionic radii of metal cations are <em>smaller</em> than those of their atoms.

Thus, the largest atoms are in the lower left corner of the Periodic Table.

The diagram below shows that K is closest to the lower left, so it is the largest atom. It is also larger than any of the cations.

Which property of a liquid increases with increasing temperature?
Nina [5.8K]
When temperature of liquid is increased, liquid gets thinner and thinner and hence it's viscosity decreases.

Density = mass/volume.

As we increase the temperature, volume of the liquid starts to increase but mass of the liquid remains constant. As a result, density of liquid decreases.

Hope this helps!
