New questions in Science. 15. C) Alkaline Earth Metals. Why this name? Although astatine is radioactive and only has short-lived isotopes, it behaves similar to iodine and is often included in the halogen group. When they form ions, they tend to gain an electron and form negative ions. None. Image showing periodicity of group numbers for group 17 chemical elements. The elements of group 16 are called (a) Chalcogens (b) Halogens (c) Pnicogens (d) Noble gases (a) Chalcogens. Group 17 elements are called. What is the atomic number of element of period 3 and group 17 of the Periodic Table? Group 17: halogens; Group 18: noble gases; In addition, groups may be idenitifed by the first element in each group - so the Group 16 set of elements is sometimes called the oxygen group. lynelle lynelle 01/21/2020 Physics Middle School Elements in group VIIA (sometimes referred to as group 17) are all called _____. 14. Learn more about the properties of halogens in this article. Question: 47) Group 17 (7A) Elements Are Also Called: A) Noble Gases. Notes. Group 17 elements are also known as: (a) halogens (2) (name still in common use) (b) Group VIIA (name no longer used) Group 17 elements are non-metals; Group 17 elements exist as diatomic molecules (X 2) when not combined with other elements. They are called “halogens” because they give salts when they react with metals. A) 0.125 B) 4 C) 8 D) 16 49) What Is The Oxygen-to-sulfur Mass Ratio Of Sulfur Dioxide?
