What element would have properties most similar to the new element?
The newest officially discovered elements are Ununquadiumand Ununhexium so, we'll focus on those.Ununquadium will be part of the Carbon series, so we would expect it to have properties similar to those elements (e.g. 4 electrons in the outer shell). The closest relation to it in that group would be Lead.Ununhexium will be part of the Oxygen series, so, again, we would expect it to have properties similar to those elements (e.g. 6 electrons in the outer shell). The closest relation to it in that group would be Polonium, which is also the first radioactive element.
Which elements woukd you expect to be similar to technetium?
Rhenium is the element most similar to technetium in terms of chemical properties and behavior due to their adjacent positions in the periodic table. Both technetium and rhenium are transition metals with similar electron configurations, allowing them to exhibit analogous oxidation states and reactivity. Additionally, both elements are used in nuclear medicine applications for diagnostic imaging.
Which chemical elements would you expect to find in abundance in a living cell?
Carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur are the most abundant chemical elements found in living cells. These elements make up the building blocks of biological molecules such as proteins, nucleic acids, lipids, and carbohydrates. Additionally, smaller amounts of other elements like calcium, potassium, and magnesium are also essential for various cellular functions.
Which of the following outer electron configurations would you expect to belong to a reactive metal?
An outer electron configuration with one or two electrons in the outermost shell would be expected to belong to a reactive metal. This is because metals tend to lose electrons to achieve a stable electron configuration, and elements with one or two electrons in the outer shell are more likely to lose those electrons easily.
How many chemical bond could you expect ekasilicon to form?
Ekasilicon (SiH4) can form a maximum of 4 chemical bonds. Silicon has 4 valence electrons which it can share with other atoms in order to achieve a stable octet configuration, resulting in the formation of 4 chemical bonds.
Which element would you expect to gain one electron in a chemical reaction?
Metals are the elements that usually lose electrons in their chemical reactions. This is because they have few electrons in their outermost shells which are easily lost.
Where on the periodic table would you expect to find elements with similar properties and chemical characteristics?
Elements in a same group have same number of valence electrons and hence similar physical and chemical properties.
Would you expect calcium to gain or lose electrons in a chemical reactions?
Calcium is expected to lose electrons in a chemical reaction because it is a metal located in group 2 of the periodic table, which typically loses electrons to achieve a stable electron configuration. Calcium will typically form a 2+ cation by losing 2 electrons in reactions.
What part of an atom is not involved in chemical reactions?
The nucleus of an atom is not involved in chemical reactions. The nucleus contains protons and neutrons, which do not participate in chemical bonding or reactions. Chemical reactions involve the electrons in the outer energy levels of an atom.
Two elements are found in the same column of the periodic table You would expect these elements to have?
same number of valence electrons, so are their chemical properties more or less the same.
Does strontium have the tendency to lose or gain electrons in a chemical reaction?
You wouldn't expect strontium to gain electrons in a chemical change.
Does titanium gain or lose electrons?
Tungsten generally loses electrons when forming bonds, it is a metal
Would you expect neodymium and uranium to similar properties?
Uranium and neodymium are very different chemical elements.
How would you expect energy to change during a chemical reaction?
Chemical reactions are either; endothermic, removing energy from the environment, or exothermic, emitting heat upon the environment.
Which elements would you expect to have chemical behavior similar to that of sodium?
I would expect all elements in group 1 to have similar chemical behavior to that of sodium, except for hydrogen. Hydrogen is not a metal, but has only 1 valence electron like the other elements in group 1.
What pair of elements do you expect to be most similar?
I expect elements with similar properties in the periodic table to be most similar. For example, elements in the same group or period tend to have similar chemical characteristics due to their similar electron configurations.
