Um i think gold... i think?
The answer is diamagnetism. It is a significant mechanical
effect that happens in all materials; when it is the only influence to the
magnetism, the material is named diamagnetic. Quartz and water are samples
of diamagnetic materials. The diamagnetic influence
is usually unimportant in materials holding strong lasting magnetic moments.
Answer:
The programs take two-dimensional images and allow the user to manipulate cubes and prisms to create their design sketches.
Explanation:
Instead of working with squares and triangles, the programs allow the users to manipulate cubes and prisms to create their design sketches. Additionally, the programs can take two-dimensional pictures and convert them to possible three-dimensional images.
I got you bro :)
Sorry he took your points :(

The decay product represented by X : Thorium (Th) : ²³⁴₉₀Th
<h3>Further explanation</h3>
Given
Decay reaction
²³⁸₉₂U ⇒ ⁴₂He + X
Required
The decay product
Solution
Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,
- alpha α particles ₂He⁴
- beta β ₋₁e⁰ particles
- gamma particles ₀γ⁰
- positron particles ₁e⁰
- neutron ₀n¹
In a decay reaction, <em>the sum of the mass number and atomic number of the elements in the reactants and products must be the same</em>
So the mass number of the element X = 238 - 4 = 234
Atomic number of the element X = 92 - 2 = 90
If we look at the periodic system, then the element with atomic number 90 is Thorium (Th)
Answer: 12 electrons
<u>If the 3d and 4s bands are superimposed on a metal atom, the maximum number of electrons for this band will be 12 electrons.</u> Remember that in layer 10 you can enter up to 10 electrons in the orbitals that you have, while the s can enter 2, therefore the amount of electrons that will enter the set formed by both bands when superimposed will be 12 electrons
