What is the contribution of Seaborg to the periodic table?
His key contributions to periodic table structure include: In 1944, Seaborg formulated the ‘actinide concept’ of heavy element electron structure, which predicted that the actinides, including the first 11 transuranium elements, would form a transition series analogous to the rare earth series of lanthanide elements.
What are the gaps in the periodic table?
The gaps represent undiscovered elements predicted by Mendeleev ’s periodic table, for example, Gallium (atomic mass 69.7) and Germanium (atomic mass 72.6) . You can read more about Mendeleev’s periodic table at the following link:
What is the name of the element that has no protons?
Neutronium is a name coined in 1926 by scientist Andreas von Antropoff for a proposed “element of atomic number zero” (i.e., because it has no protons) that he placed at the head of the periodic table. In modern usage, the extremely dense core of a neutron star is referred to as “degenerate neutronium”.

The version shown below, in the International Union of Pure and Applied Chemistry (IUPAC) format, accounts for elements up to atomic number 118 and color-codes 10 different chemical series.

How sure are we that nuclear fusion reactors are possible?
I know that nuclear fusion occurs in labs all the time here on Earth and that there are a few different groups trying to make a fusion reactor where you get more energy out than you put in.
Similar to a recently asked question. If 2 cars travel at half the speed of light or more toward opposite directions, will the relative speed from one car to another be more then the speed of light?
If so, how will the time and the space work for the two cars? Will they see each other tighter?
Can an individual's blood carry a cure for a virus outbreak like the movies?
I've read there are some experiments suggesting plasma from covid survivor's could help fight the spread. Though it got me wondering how much truth is in the possibility of one persons blood being the key to a widespread virus like many movies.
Can nuclear waste still be used for energy?
As far as I'm aware, waste fuel from nuclear power plants is still radioactive/fissile. Seeing as waste management seems to be the biggest counterpoint to nuclear energy, what can be done with the waste?
How does Europa have liquid water?
I've always understood the habitable zone to be the only distance where liquid water could exist on a planet. Any closer and it would evaporate, any further and it would freeze. The habitable zone for our sun is 0.9 - 1.5 au, yet Jupiter is 5.2 au on average from the sun with the closest distance being 4.95 au.
Is two 50mph cars crashing same as 100mph car crashing into tree?
If two cars crash into each other going 50 miles per hour, is that the same force generated as just one car going 100 miles per hour crashing into a tree (any still object)?

How do they know that the skull found in Harbin (AKA Dragon Man) belonged to a male and not a female?
I was just reading an article about it, and there was a drawing of a male Homo longi, and I thought, why couldn't it be a female? Is there a scientific way of knowing that from the skull, considering that their characteristics differ from H.Sapiens?
Why is chickenpox more dangerous for adults?
Adults get more dangerous symptoms and are more likely to die because of chickenpox but why does it hit adults so much worse than children? Google couldn't tell the reason. It only told it is worse for adults but didn't tell why.

What are the elements that are beyond actinides?
Heavier elements beyond the actinides were first proposed to exist as early as 1895, when the Danish chemist Hans Peter Jørgen Julius Thomsen predicted that thorium and uranium formed part of a 32-element period which would end at a chemically inactive element with atomic weight 292 (not far from the 294 known today for the first and only discovered isotope of oganesson ). In 1913, the Swedish physicist Johannes Rydberg similarly predicted that the next noble gas after radon would have atomic number 118, and purely formally derived even heavier congeners of radon at Z = 168, 218, 290, 362, and 460, exactly where the Aufbau principle would predict them to be. Niels Bohr predicted in 1922 the electronic structure of this next noble gas at Z = 118, and suggested that the reason why elements beyond uranium were not seen in nature was because they were too unstable. The German physicist and engineer Richard Swinne published a review paper in 1926 containing predictions on the transuranic elements (he may have coined the term) in which he anticipated modern predictions of an island of stability: he had hypothesised since 1914 that half-lives should not decrease strictly with atomic number, but suggested instead that there might be some longer-lived elements at Z = 98–102 and Z = 108–110, and speculated that such elements might exist in the Earth's core, in iron meteorites, or in the ice caps of Greenland where they had been locked up from their supposed cosmic origin. By 1955, these elements were called superheavy elements.
What is the seventh period in the periodic table?
An extended periodic table theorises about chemical elements beyond those currently known in the periodic table and proven, up to oganesson, which completes the seventh period (row ) in the periodic table at atomic number ( Z) 118. As of 2021. , no element with a higher atomic number than oganesson has been successfully synthesized;

The first attempts to synthesize unbibium were performed in 1972 by Flerov et al. at the Joint Institute for Nuclear Research (JINR), using the heavy-ion induced hot fusion reactions:
Which element can easily form a +8 oxidation state?
In the first few superactinides, the binding energies of the added electrons are predicted to be small enough that they can lose all their valence electrons; for example, unbihexium ( element 126) could easily form a +8 oxidation state, and even higher oxidation states for the next few elements may be possible.
Why are 7D transition metals not noble?
The noble metals of this series of transition metals are not expected to be as noble as their lighter homologues, due to the absence of an outer s shell for shielding and also because the 7d shell is strongly split into two subshells due to relativistic effects. This causes the first ionization energies of the 7d transition metals to be smaller than those of their lighter congeners.
How many neutrons are in a 3n reaction?
No atoms were identified, leading to a limiting cross section of 300 nb. Later calculations suggest that the cross section of the 3n reaction (which would result in 299 Uue and three neutrons as products) would actually be six hundred thousand times lower than this upper bound, at 0.5 pb.
What is the g block?
According to the orbital approximation in quantum mechanical descriptions of atomic structure, the g-block would correspond to elements with partially filled g-orbitals, but spin-orbit coupling effects reduce the validity of the orbital approximation substantially for elements of high atomic number.
