My Element Collection Is Halfway Complete

Описание: Just in case you didn’t see my post from this week, I am going to give you an update on my element collection in video format. I just reached the halfway point of my collection, and I got 49 elements, but technically there’s 48, but one is on its way to my house. I am trying to get all the elements up to americium (element 95), and it will be challenging, and that’s because the other half could be any of these four things:
1. Super expensive
2. Annoyingly toxic
3. Reactive with water
4. Radioactive
These are the elements I am missing:
1. Hydrogen
2. Helium
3. Lithium
4. Beryllium
5. Boron
7. Nitrogen
8. Oxygen
10. Neon
11. Sodium
15. Phosphorus
17. Chlorine
18. Argon
19. Potassium
20. Calcium
23. Vanadium
34. Selenium
36. Krypton
37. Rubidium
38. Strontium
42. Molybdenum
43. Technetium
44. Ruthenium
46. Palladium
47. Silver
48. Cadmium
54. Xenon
55. Cesium
56. Barium
58. Cerium
60. Neodymium
61. Promethium
63. Europium
64. Gadolinium
70. Ytterbium
76. Osmium
77. Iridium
78. Platinum
80. Mercury
85. Astatine
87. Francium
88. Radium
89. Actinium
90. Thorium
93. Neptunium
94. Plutonium
95. Americium
(Scandium, #21, is technically also missing, but it is currently on its way here, and I’ll make a video on it once my sample arrives in the mail, and it is also my first element in the second half of elements I’ve collected)
