Here's the pattern I came up with:1 = 123 = 3 x 204 = 226 = 3x219 = 3212 = 3x2216 = 42so using this pattern above the next number should be 3x23 or 24.

The number that comes after 225 is 226. This follows the basic counting sequence in which each number increases by one.
The equation for alpha decay from radium-226 (Ra-226) can be represented as follows: [ \text{Ra-226} \rightarrow \text{Rn-222} + \alpha ] In this equation, radium-226 (Ra-226) emits an alpha particle (α), which is essentially a helium nucleus, resulting in the formation of radon-222 (Rn-222). This process decreases the atomic number by two and the mass number by four.

The missing number in this sequence is 64, or 4 raised to the third power. You find the answer by noting that each number in the sequence is a counting number starting at 1 that is raised to the third power. For example, 2 raised to the third power (2 x 2 x 2) is 8.
Country code +226 is Burkina Faso, and +226 72 is a Telmob mobile. The remainder of the number will be six more digits.
Radium has an atomic number of 88, meaning it has 88 protons. The most common isotope of radium is radium-226, which has a mass number of 226. This mass number represents the total number of nucleons (protons and neutrons) in the nucleus, so radium-226 has 226 nucleons.
no but 225 is
Yes, it is.
Radium has several isotopes, but the most common one is radium-226. This isotope has an atomic number of 88, indicating it has 88 protons. Since the mass number of radium-226 is 226, it contains a total of 226 nucleons, which includes both protons and neutrons. Therefore, radium-226 has 138 neutrons (226 - 88 = 138).
The most stable isotope of radium - 226Ra - has the atomic mass 226,025 409 8 (25).
The number 226 would be scientifically noted as 2.26 x 10^2.
