# Hydrogen # Helium # Lithium # Beryllium # Boron
Both nitrogen and phosphorus are in group 5 of the periodic table because they have 5 valence electrons. This group is known as the nitrogen family or group 15. Both elements have similar chemical properties due to their shared electron configuration.
The fifth element on the periodic table of elements is boron. It has an atomic number of 5 and is a metalloid with various industrial applications.
Xenon is in Group 18, the "inert" elements.
Period 5 of the periodic table contains 18 elements, starting with rubidium (37) and ending with xenon (54).
Vanadium Niobium Tantalum
well, hydrogen, oxygen, helium, neon, nitrogen. honestly? the periodic table? the first 5 elements on the periodic table are non metals
Hydrogen, Helium, Lithium, Beryllium, Boron
Group 5 (a)
Group 11 and Period 5
These are the periods 4 and 5.
Elements such as iron, copper, zinc, and gold in table 1 are metals. Metals are typically found on the left and center of the periodic table.
Period 4 and period 5 of the periodic table have the same number of elements. There are 18 elements in each period. While some elements in period 4 are calcium, iron, and zinc, elements in period 5 are tin, antimony, and iodine.
lanthanides
Both nitrogen and phosphorus are in group 5 of the periodic table because they have 5 valence electrons. This group is known as the nitrogen family or group 15. Both elements have similar chemical properties due to their shared electron configuration.
There is no "row 15" in any periodic table I have ever seen. There is a column 15 in a wide form periodic table, which contains the stable elements nitrogen, phosphorus, arsenic, antimony, and bismuth, for a subtotal of 5, and may contain one of the very heavy and radioactive elements recently made.
The six elements commonly recognized as metalloids are boron, silicon,germanium, arsenic, antimony and tellurium. So that is six elements out of 112 elements or 5.4%
