What is the group seven called in the periodic table?
Group 7 elements are examples of transition metals (or d-block elements)
What are rows called in Periodic rable?
Rows in the periodic table are called periods. There are seven periods in the periodic table which represent the energy levels of the elements. Each period signifies the number of electron shells an element has.
Which group cotains the most elements?
Group one has seven known elements, the most of any of the 18 groups on the periodic table so far.
What is the name given to the elements in group Vila of the periodic table such as fluorine and chlorine?
They are called halogens. They are in the 17th period. They have 7 electrons in the outermost energy level.
What are horizontal rows of elements are called?
periodsThere are seven periods, or rows, on the Periodic Table.
What is the horizontal column of elements called?
periodsThere are seven periods, or rows, on the periodic table.
What are horizontal rows called in a periodic table called?
Horizontal row in a periodic table is called Period.There are seven periods in a periodic table.All elements in a row have same number of electronic shells.
What is group seven on the periodic table?
Group seven on the periodic table refers to the halogens. This group includes fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form compounds with other elements.
What are the elements reactivity in group seven in the periodic table?
elements in group 17 need one more electron to attain the nearest noble gas configuration, hence they are more reactive
What are elements in group 17 called?
halogens
How many elements make up group 7 in the periodic table?
atoms that occur as 2 atom molecules (N,O,F,Cl,Br,I,H) ================ The Rule of Seven refers to seven specific elements on the Periodic Table that share certain properties. These elements are hydrogen (H2), Oxygen (O2) Nitrogen (N2) Flourine (F2), chlorine (Cl2), bromine (Br2) and iodine (I2). The positions of these seven elements form the shape of a 7 on the periodic table. The properties they share are these: They have the greatest stability in the diatomic (2 atom) form, and they are bonded covalently.
Group 7 in the periodic table?
Group 7 in the periodic table is known as the halogens. The elements in this group include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Halogens are highly reactive nonmetals that have seven electrons in their outermost energy level.
