How many valence electrons for this element having this electron configuration 1s2 2s2 2p6

Chemistry
1 answer:
Radda [10]3 years ago
4 0

Answer:

1 {s}^{2} 2{s}^{2} 2 {p}^{6}

The outermost shell holds the so called valence electrons, therefore we have 8 electrons in that shell...

2s have 2 electrons and 2p hold 6 electrons 6+2=8

you are holding a bowling ball with a mass of 6 kg at a height of 1 meter. How much gravitational potential energy does the bowl
Bumek [7]

The formula for GPE is PE=mgh, where “m” is the mass of the object, “g” is the acceleration due to gravity (~9.8 m/s^2 on Earth’s surface), and “h” is the height of the object from the ground. Therefore,

PE=mgh

PE=(6 kg)(9.8 m/s^2)(1 m)

PE=58.8 kg•m^2/s^2 or 58.8 Newtons

The GPE of the bowling ball under these conditions would be about 59 Newtons.

Hope this helps!

If the [H3O+] of a solution is 1x 10-8 mol/L the [OH-] is
Studentka2010 [4]

Answer:

<em>(H30+)= 1x10^-6 M</em>

Explanation:

Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:

1x 10-8 mol/L equals to1x10-8 M

(H3O+) x (OH-) = 1x10^-14

(H30+)x 1x 10^-8 =1x10^-14

(H30+)= 1x10^-14/1x 10^-8

<em>(H30+)= 1x10^-6 M</em>
