What is the symbol for fluorine? What is the symbol for bromine? What is the chemical element sulfur? What chemical element has the symbol S? What is the symbol for the chemical element hydrogen? What is the chemical symbol for gold?
What is the oxidation number of bromine in the BrO_3^- ion? a) Which element is oxidized and which is reduced in the reaction ? 6 Li(s) + N2(g) \rightarrow 2 Li3N(s) b) Which atom is oxidized and which is reduced in the reaction ? Sr(s) + 2 H2O(l) \rightarrow Sr^{2+...
So bromine has 35 protons and 35 electrons, but 45 neutrons. Platinum has 78 protons, 78 electrons, and 117 neutrons. The number of protons in an atom is called the atomic number and it tells you what type of atom you have. An atomic number of 1 means the atom is hydrogen, atomic ...
Similarly, when Bromine is added to a solution of Potassium Iodide, it replaces the position of Iodine in the compound. As a result, Potassium Bromide is formed, whereas a molecule of Iodine is given out. This reaction takes place because Bromine is more reactive than Iodine, which is why ...
Which of the following ions have a complete valence-shell octet? B^+, I^-, Ca^2+, or Pb^2+ What noble gas has the same electron configuration as the magnesium ion? To achieve an octet, the oxygen atom forms an ion. What is the name of this ion? Based on the octet rule, iodi...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
is 0.68×10-10m. Because W6+ has a small ion radius, high electricity price, strong polarization ability, and is easy to form complex anions, tungsten is mainly in the form of complex anions [WO4]2-, which combines with Fe2+, Mn2+, Ca2+ and other cations in the solution to form ...
What is the origin name of astatine? Because astatine has no stable or long-lived isotopes, it was given its name fromthe Greek word astatos, meaning “unstable.” Who discovered plutonium? On March 21, 1942, the chemical element with the atomic number 94 was given the name plutonium, afte...
For instance, if your PCB is to be conformal coated (in order to protect the circuitry during operation), the board surface has to be completely free of all flux residues. No-clean flux can leave behind minimal residues, preventing the good adhesion of conformal coating. While no-clean ...
Electronegativity is the measure of an atom’s ability to attract additional electron density to itself. For example, Sodium seeks togivean electron to become a positive ion, Na+. It has a very low electronegativity. Iodine wants togainan electron to become a negative ion, I–. It has a ...
