Answer:
z≅3
Atomic number is 3, So ion is Lithium ion ()
Explanation:
First of all
v=f*λ
In our case v=c
c=f*λ
λ=c/f
where:
c is the speed of light
f is the frequency
Using Rydberg's Formula:
Where:
R is Rydberg constant=
z is atomic Number
For highest Energy:
n_1=1
n_2=∞
z≅3
Atomic number is 3, So ion is Lithium ion ()
Answer:
6.2moles of Gold
Explanation:
To solve this problem, we are going to use the mole concept approach.
Given that;
Number of atoms of gold is 3.73 x 10²⁴ atoms
Now;
In 1 mole of any substance, we have 6.02 x 10²³ atoms;
So;
If there 6.02 x 10²³ atoms in 1 mole of any substance;
3.73 x 10²⁴ atoms will contain = 6.2moles of Gold
