Is silicon a cation or anion?
It isn't necessarily a cation. However, the vast majority of silicon on earth is in the form of silicates, where it is formally positively charged. That makes the statement at least sort of true.
What is true of iodine and radioactive iodine a-Both have the same atomic number b-Both have the same number of electrons c-Both have the same number of neutrons d-None of the ab?
both a and b are true for iodine and radioactive iodine isotope
The element iodine is a halogen True or false?
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
T4 has four atoms of iodine in every molecule?
true
What is true about both fluorine and oxygen that allow them to pull hard on electrons?
Fluorine and oxygen are non metals. They pull hard the electrons.
Does Iodine have less electron affinity than fluorine?
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
Why group 7 elements get more reactive as you go down the group from fluorine to iodine?
There can not be any reason, because the premise is not true: Group 7 elements become less rather than more reactive from fluorine to iodine.
Is fluorine Chlorine and bromine metals?
true
What is true or same about both chlorine and iodine?
Chlorine and iodine are both non-metals Neither are radioactive They are both made in nature
Why is the element oxygen found in nature as oxygen 2?
Because of its various properties, oxygen must always occur in nature as an ionic bound or O2. This is also true for Hydrogen, Fluorine, Bromine, Iodine, Nitrogen, and Chlorine.
What is percentage of iodine in sodium?
Zero: Iodine and sodium are both chemical elements, and neither contains any of the other, as is true for all pairs of different elements,
What is the metalloid with 7 valence electrons?
halogens
Chlorine is a very reactive nonmetals?
Yes!!! Agreed Chlorine gas is a very reactive non-metal. Fluorine, which is in the same group is even more reactive non-metal. Fluorine is often nicknamed the 'Tyrannosaurus Rex' of the elements, because of its high degree of reactivity. In the lab. take a gas jar full of chlorine, and place a pellet of sodium metal in it. They will immediately react to form sodium chloride (NaCl) common table salt.
What four elements have chemical properties like fluoride?
Flourine belongs to a class of elements called Halogens, which are similar in their chemical and physical properties. The other elements of this group are Chlorine, Bromine, Iodine, Astatine and Ununseptium. Astatine, however, is not considered to be a true halogen since it is radioactive in nature and Ununseptium is a synthetic element.
What are the similarities between electronic structure of sodium and fluorine?
There is no particular similarity between the electronic structure of the elements sodium and fluorine. Their electronic structures are similar only to the extent that all elements have certain features in common. The electrons form shells around the nucleus. This is true of sodium and fluorine as well as all other elements.
Is the elements ability to form a compound with chlorine a physical property?
No, it is a true chemical property !
What compound is chlorine?
Chlorine is not a compound, it is a basic element. It is 17th on the periodic table of elements and has a mass number of 35.45. - - - - - Having said that, which is true, chlorine is so reactive it'll go out of its way to form compounds with other elements.
