12 stycznia 2021

Explanation: The elements in-group 7 are often referred as “halogens”. Elements in a group have the same number of energy levels and the same valence electrons. The elements of group 16 are called (a) Chalcogens (b) Halogens (c) Pnicogens (d) Noble gases (a) Chalcogens. For example, flourine reacts explosively with sodium to form sodium fluoride. Group 17 Elements. All halogens have the same a. atomic number. B) Halogens. Units. Notes. D) Alkali Metals. They are called “halogens” because they give salts when they react with metals. There is considerable confusion surrounding the Group labels. 15. Question: 47) Group 17 (7A) Elements Are Also Called: A) Noble Gases. 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. 1- The elements in this group are all non metals. The group 17 elements include fluorine(F), chlorine(Cl), bromine(Br), iodine(I) and astatine(At) from the top to the bottom. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). When they form ions, they tend to gain an electron and form negative ions. (a) 10 (b) 4 (c) 17 (d) 21 (c) 17. Why this name?

Let’s now look at the electronic configuration of these elements. Although astatine is radioactive and only has short-lived isotopes, it behaves similar to iodine and is often included in the halogen group. 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. lynelle lynelle 01/21/2020 Physics Middle School Elements in group VIIA (sometimes referred to as group 17) are all called _____.
