An ionic bond is when the atoms transfer electrons, rather than share electrons. This gives the ionically bonded elements a charge.

Unlike ionic bonds, covalent bonds involve the sharing of electrons between atoms.

Answer: C. sharing of electrons between atoms.

What is the speed of an electron that has a de Broglie wavelength of 100. nm?

Advocard [28]

Answer: The speed of the electron is $7.24\times 10^3m/s$

Explanation:

To calculate the speed of electron for given wavelength, we use the equation given by De-Broglie's, which is:

$\lambda=\frac{h}{mv}$

where,

$\lambda$ = De-Broglie's wavelength = $100nm=100\times 10^{-9}m$

h = Planck's constant = $6.6\times 10^{-34}Js$

m = mass of the electron = $9.11\times 10^{-31}kg$

v = speed of the electron = ?

Putting values in above equation, we get:

$100\times 10^{-9}m=\frac{6.6\times 10^{-34}Js}{9.11\times 10^{-31}kg\times v}\\\\v=\frac{6.6\times 10^{-34}Js}{9.11\times 10^{-31}kg\times 100\times 10^{-9}m}=7.24\times 10^3m/s$

Hence, the speed of the electron is $7.24\times 10^3m/s$

Gre4nikov [31]

Answer:

Surface tension

Explanation:

A water strider (water bug) is able to walk on water because of water’s Surface tension.

Surface tension is phenomenon in which in liquid where it shrinks itself to its minimum surface area possible, it is very much visible in water surface because of high attraction between the water molecule.
