WebThe elements in group 1 are called the alkali metals. Group 1 is on the left-hand side of the periodic table The alkali metals share similar physical properties . WebThe atomic number of each element increases by one, reading from left to right. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Atomic number

Therefore, period 1 has exactly two elements. Although both hydrogen and helium are in the s-block, neither of them behaves similarly to other s-block elements. Their behaviour is so different from the other s-block elements that there is considerable disagreement over where these two elements should be placed in … See more A period 1 element is one of the chemical elements in the first row (or period) of the periodic table of the chemical elements. The periodic table is laid out in rows to illustrate periodic (recurring) trends in the chemical behaviour … See more All other periods in the periodic table contain at least eight elements, and it is often helpful to consider periodic trends across the period. … See more Hydrogen Hydrogen (H) is the chemical element with atomic number 1.
