Chemistry
1 answer:
navik [9.2K]3 years ago
3 0

Answer:

The metals in this group are lithium, sodium, potassium, rubidium, cesium, and francium. The gas hydrogen is also put in this group because it shares similar reactivity with the alkali metals.

I don't know if this is what you wanted or not sorry if it isn't

How to make slime less sticky
topjm [15]
There are a few things you can do to make slime less sticky. You can either:
1) add a bit of baking soda (one to three tea spoons depending on how big it is, for the one that you show I would say one should be enough)
2)You can place it in hot water and squish the water out of it before placing it in cold water and then drying it out a bit with a towel. Don't forget to knead it a bit so it stays smooth and not too hard.

The element vanadium had a line with a wavelength of 318.5 nm in its emission spectrum. What is the frequency of this line
Hunter-Best [27]

The frequency of this line of vanadium  is 9.38 x10 ^14 Hz.

Emission spectrum shows how the electron of an atom goes or moves  from a higher to a lower energy level.

Now The energy of a photon is given by

E = hc/λ

where  

h = Plank's constant =  6.626 x 10⁻³⁴ J s

c = speed of light=   3 x 10⁸ m/s

λ = wavelength =  318.5  x 10⁻⁹ m  

Solving

E =  (6.626 x 10⁻³⁴ J s x 3 x 10⁸ m/s)  / 318.5  x 10⁻⁹ m

E =6.2166 x10 ^-19 J

Also, we know that energy is related to frequency by the equation

E =hf

Where;

h = Planks's constant

f = frequency of photon

Making frequency subject of the formulae

f = E/h

f =6.2166 x10 ^-19 J/  6.626 x 10⁻³⁴ J s

f =  9.38 x10 ^14 Hz
