9 This question is about elements in Group 1 of the Periodic Table.(a)Which statement is correct about lithium?(1) A lithium is a non-metal B lithium forms a sulfate with the formul a LiSO, C lithium reacts with water to form an alkali D lithium reacts with water to form a white...
What is the difference between an isotope and an element? What is the mass number of an isotope? What is the radioactive isotope of carbon? What is a metastable isotope? What is the symbol for the element with atomic number 74? What is a radioactive isotope? Which isotope of lithium has...
The values k H / k D for α-deuterium kinetic isotope effects for the reaction of methyllithium and methylmagnesium iodide with a series of substrates are consistently ca. 10–15% higher for the lithium reagent than for the Grignard reagent. This may indicate a pre-equilibrium between an ...
First of all, NASA will use Webb to detect deuterium in Mars’ atmosphere. Deuterium is an isotope of hydrogen and it too can form water molecules. These have more mass, though, giving them the name heavy water. Heavy water is naturally occurring and exists along side normal water in a ...

Lithium (Li), an element of considerable industrial importance, is particularly prevalent in battery production for electronic devices and electric vehicles. Exploitation of this resource is experiencing a dramatic increase in demand and this growth is expected to continue significantly in the coming ...
To directly assess the contribution of B12supplementation to SAM generation, we performed stable isotope labelling (SIL) with13C-labelled serine. Serine significantly decreases in the serum during in vivo reprogramming (Extended Data Fig.4b) and can contribute as a methyl donor to 1C metabolism (...
(i)Write an equation to represent the first ionisation energy of hydrogen.Include state symbols.(ii)The sequence of the first three elements in the Periodic Table is hydrogen,helium and then lithium.Explain why the first ionisation energy of hydrogen is less than that of helium,but greater ...
How can you calculate the number of neutrons (n) in an atom? What is the mass number of the isotope lithium-7? How do you find the mass and fractional abundance of an isotope? Bromine has two naturally occurring isotopes (Br-79 and Br-81) and an atomic mass of 79.904 amu. a. If...
