a. Cl2 b. Br2 c. I2As we go down a column on the periodic table, do metals become more reactive or less reactive? Explain.What is the first element in the periodic table in the current order?In the periodic table, K is the symbol for which element?
What is disproportion of chlorine?Answer and Explanation:Hello. Disproporation is when an element is simultaneously reducing and oxidizing. Cl2 in H2O gives you HCl and HClO. The HCl gains an electron (reduced) and the HClO loses an electron (oxidized) so the Cl is both reduced and ...
Mercury is a fascinating element that exists in various forms, including mercuric and mercurous compounds. These two forms of mercury have distinct attributes and properties that make them unique. In this article, we will explore and compare the characteristics of mercuric and mercurous, shedding ligh...

科学的可靠性还源于科学界具有公认的评价准则，所以能对理论取得一致意见，因此在比较成熟的科学领域，一个问题无论问哪一个科学家，都可以得到大致相同的答案。哲学、伦理学等学科没有公认的评价准则，同一个问题问不同的科学家或伦理学家可能得到完全相反的结果，令人无所适从。从这段文字中，能够获取的信息是：
In a binaryioniccompound, one of the elements is Cl.Which of the following would the other element most likely to be? Cl I Mg Br Binary = two parts Since Cl-Cl would be covalent – not right and the same would be for the other halogens:I, and Br. Mg is a metal forms a cation...
