WebGroup 7 - Halogens (non metals) Halogens. -Non-metals. -Have similar reactions to each other because if they can gain one electron they can each complete their outer shell. Reacting with metals. -React with metals to form compounds called halides. Reactivity. -The reactivity decreases as you go down the group. Webalkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids). Sodium and potassium are the sixth …

WebSimilar to alkali metals, hydrogen has 1 electron in its outermost shell and can form compounds with non-metals (such as HCl, etc.). However, it has non-metallic ... Because hydrogen is a nonmetal and forms H- (hydride anions), it is sometimes placed above the halogens in the periodic table. Why hydrogen can be placed in group 17 in the first ... Web1 okt. 2024 · The correct answer is option 2 i.e Alkali metals.. The electronic configuration of hydrogen resembles that of Alkali metals.; Hydrogen is similar to both alkali metals and to halogens.; This is because alkaline-like hydrogen metals donate their outer electron to form compounds such as oxides, halides & sulfides.; It also shares the electron of its with … how big is a beach ball

WebHalogens. Alkali metals are s-block elements found on the periodic table’s left side. Halogens are the elements of group 17. Caesium, hydrogen, lithium, sodium, rubidium, francium, and potassium. Fluorine, astatine, bromine, iodine, and chlorine. The elements of alkali metals easily lose electrons in their outermost layer. WebSimilar hydrogen bonding exists in the other hydrogen halides, but it is considerably weaker. The large difference in hydrogen bonding between hydrogen fluoride and the other hydrogen halides accounts for the relatively high melting and boiling points of hydrogen fluoride as compared with those of hydrogen chloride and the other … Web15 mrt. 2024 · The halogens react with hydrogen to produce compounds called hydrogen halides. For example, chlorine reacts with hydrogen: Hydrogen + chlorine → hydrogen chloride H2(g) + Cl2(g) → 2HCl...
