What is the noble gas that has the same Lewis structure as Se2?
The element (noble gas) Krypton
What is one way the electronic structure of the atoms of group2 element are the same?
All group 2 element have same outmost shell (2)
Allotropes have different what?
Allotropes are versions of the same element or compound with a different molecular structure.
What noble gas has the same Lewis structure as Se2-?
Krypton and Selenide ion have 36 electrons and are isoelectronic
This element is in the same family as silver and gold?
Copper is an element that is in the same family as gold and silver. All of these metals are in the same group on the periodic table. Because of their similarities in structure, these metals have similar properties
What is the noble gas that has the same Lewis structure as Se2?
The element (noble gas) Krypton
What element has the same Lewis dot structure as sulfur?
No
Which element would you expect to have a Lewis symbol similar to that of sulfur?
Oxygen, Selenium, Tellurium, or any other element in the same group as sulfur would have a similar Lewis symbol.
What is one way the electronic structure of the atoms of group2 element are the same?
All group 2 element have same outmost shell (2)
What noble gas has the same Lewis structure as Se2-?
Krypton and Selenide ion have 36 electrons and are isoelectronic
Allotropes have different what?
Allotropes are versions of the same element or compound with a different molecular structure.
What is the Lewis structure CH3CO2H?
CH3CO2H also known as acetate is an acid used in everyday life. The formula of vinegar is same as acetate, which means vinegar and acetate are the same things. The chemical formula can also be written as CH3COOH.
How do the number of electrons compare in two isotopes in an element?
In a neutral atom, the number of electrons equals the number of protons. Isotopes of the same element also have the same number of electrons and the electronic structure.
This element is in the same family as silver and gold?
Copper is an element that is in the same family as gold and silver. All of these metals are in the same group on the periodic table. Because of their similarities in structure, these metals have similar properties
Which of the following elements has the same Lewis dot structure as phosphorus?
N and As for two. They all have 5 valence electrons (as do Sb and Bi).
Why is it better to arrange elements according to their electronic structure and not in order of their relative mass number?
The chemical properties of any given element are the result of it electronic structure. The mass number is not related to the electronic structure because the mass includes neutrons, which not related to the electron structure (unlike protons). Any given element exists in more than one form (called isotopes) which have different numbers of neutrons, but the same electronic structure (and the same number of protons).
Why can the structure of a metallic element like copper be represented by lots of small spheres the same size packed together?
They are atoms of the same element. They are packed together because the bonds between them are strong thus forming a solid
