Elements in the same group have the same number of electrons in their outermost shell hence their chemical properties are usually similar to one another. Answer and Explanation: a) Lithium belongs to the first group (Group IA). Hence, it has the same or ...
Similarly, beryllium, chromium, lithium and natrium (sodium) become berili, crôm, liti, and natri, respectively The -gen suffix is lost, e.g., nitrogen, oxygen and hydrogen become nitơ, ôxy and hiđrô, respectively A minority of elements without--or with etymologically unclear--...
Scientists have determined that all chemical elements in the universe besides hydrogen and helium (and a trace amount of lithium) were produced by stars. These are known as heavy elements because they are heavier than hydrogen and helium. lthough all of these heavy elements are quite rare ...
1-20: Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Sodium, Magnesium, Aluminium, Silicon, Phosphorus, Sulphur, Chlorine, Argon, Potassium, Calcium. Elements that have similar chemical properties are grouped in columns called groups (or families). alka...
The biennial review of determinations, (E), and other cognate data has warranted no changes for the of the elements from that previously published in the Table of Atomic Weights 1995 with the exception of a new footnote for lithium. The names for the transfermium elements with atomic numbers ...
Which pair of elements do you expect to be most similar? Why? a) nitrogen and oxygen. b) titanium and gallium. c) lithium and sodium. d) germanium and arsenic. e) argon and bromine.Name the four common halogens and tell the normal phase...
Although all of these heavy elements are quite rare compared to hydrogen and helium, they are found just about everywhere. According to paragraphs 1 and 2, living cells contain which of the following? All chemical elements in the universe except lithium About 25 different elements About 96 ...

Elements in each group have similar but not identical ___. For example, lithium (Li), sodium (Na), potassium (K), and other members of group IA are all soft, white, shiny metals. All elements in a group have the same number of ___ ___. Periods Each horizontal ___ of elements...
It is a fluorinated (0.74±0.005 mg/L) mineral water, rich in Magnesium (42±0.09 mg/L), Calcium (93±0.09 mg/L), Sodium (210±0.08 mg/L), Lithium (0.012±0.02 mg/L) and poor in harmful and toxic Trace Metals, including Aluminum (<0.002 μg/L) and heavy metals Lead (<0.0005...
