How a chemist can state with certainty that no one will discover an element that would appear on the periodic table between sulfer C and chlorine Cl?
Explain how chemists can state with certainty that no one will discover an element between sulfur (S) and chlorine (Cl). Answer: Chlorine has an atomic number one greater than sulfur. This means it has one more proton in its nucleus.
What is an example of an element How do scientists know it’s an element?
An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. If you change the number of protons an atom has, you change the type of element it is.
What can you predict about an element in the periodic table?
The periodic table of the elements places the elements according to their atomic number, electronic configuration and chemical properties. Thus, depending on the location of an element in the periodic table, we can guess its electronic configuration and more importantly, its properties.
What is the difference between sulfur and chlorine?
Sulfur contains 16 massive charged particles, and 16 oppositely charged particles of negligible mass. Chlorine contains 17 massive charged particles, and 17 oppositely charged particles of negligible mass.
What is the purpose of the zigzag line on the periodic table?
The line of separation between metals and nonmetals is the zigzag line. This zig zag line contains metalloids. These include antimony, germanium, boron, silicon, arsenic, tellurium and polonium. The zigzag line in the periodic table separates metals from nonmetals.
What can you infer about copper and silver based on the position relative to each other?
What can you infer about copper and silver based on their position relative to each other? Atoms of copper and silver have the same number of valence electrons. There is no whole number between these two numbers so an element cannot appear between them.
How do scientists discover new elements?
(The atomic number refers to the number of protons in an atom’s nucleus.) Beyond that, scientists must create new elements in accelerators, usually by smashing a beam of light atoms into a target of heavy atoms. Every so often, the nuclei of the light and heavy atoms collide and fuse, and a new element is born.
How can you predict the state of an element?
The state of a substance at a given temperature can be predicted if its melting point and boiling point are known.
Which element has chemical properties similar to sulfur?
Nonmetal
ChalcogenPeriod 3 element
Sulfur/Chemical series
Are sulfur and chlorine in the same period?
The third period contains eight elements: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine, and argon.
How can the zigzag line on the periodic table help you?
How can the zigzag line on the periodic table help you? It helps you recognize which elements are metals, which are nonmetals, and which are metalloids.
