Answer:

2

Explanation:

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

Hello Gary!
*Sorry if I'm late*

Your answer is going to be 65.
Element A (which is actually Zinc) has the atomic number of 65. (I remember having got memorize this also).
Pretty much the explanation is that the number of patrons is equivalent to the element's atomic number!

Hope this helps!
Have a nice day :D

The barometer would show a decrease in wind speed resulting in the disipation of cloud cover because of the lack of wind, and also because the temperature is dropping there is less precipation because there is no hot air rising to create clouds :)

Suppose that the uncertainty in determining the position of an electron circling an atom in an orbit is 0.4 A. What is the uncer
dolphi86 [110]

Answer:

Explanation:

Applying the Heisenberg uncertainty principle,

Δx X mΔv = h/4π

where Δx = uncertainty in measurement of position

Δv = uncertainty in measurement of velocity

m = mass of object

h = planck's constant

Here:

Δv = 0.4 A° = 4.0 x 10^-11 m

mass, m = 9.11 x 10^-31 Kg

Plugging the values,

4.0 x 10^-11 x Δ v = (6.626 x 10^-34) / (4 x 3.14 x 9.11E-31)

4.0 x 10^-11 x Δ v = 5.791 x 10^-5

Δv = 1.448 x 10^6 m/s, the uncertainty in its velocity

Answer = 1.45 x 10^6 m/s
