The element's determines how the compound will form?
It's outer valence electron shell(s).
Is fruit an ionic compound or covalent?
Eggs are a complex mixture of principally organic compounds, including proteins. The bonding is therefore principally covalent in the many compounds that make up an egg. The most obvious ionic compound is in the shell, and that is calcium carbonate.
Why are halogens only in compound form?
This has to do with the number of electrons in the outer shell of the element. Simply put, each element has a certain number of electrons, equal to their atomic number on the periodic table. These electrons are found in "shells," and ideally, the outer shell has 8 electrons in it. If it does not, the element will bond with another element, giving or receiving electrons so that the element has a completed outer shell (8 electrons). The halogens all have an outer shell of 7 electrons. They are only one short of a completed outer shell, and therefore it is very easy and desirable for them to pick up an electron from another element, forming a compound and giving them a full, stable outer shell. For example, in the case of sodium chloride (NaCl), sodium has only 1 electron in its outer shell (called a valence electron), while chlorine has 7. It is very easy for sodium to lose that one electron to chlorine, completing chlorine's outer shell and creating a very stable compound. Because halogens so readily attract electrons to form compounds and are so much more stable as compounds than as elements, they are very rarely found not in compound form.
Is neon gas a homogeneous or heterogeneous?
no, Homogeneous is a term used when talking about a mixture. It means to have the same appearance through out the mixture. Neon is a noble gas and a single element. unless ur talking about neon and some other molecule or compound this term does not apply. neon is a noble gas. all noble gasses have a full outer shell (octet rule). all elements on the table react and strive to achieve this because having a full outer shell makes the element un-reactive and reduces the energy in that element tremendously.
Is a shell a mixture?
Yes! You can pull or separate the shells from the sand or sand from the shell.
Is hydrogan gas a compound or a mixture?
It is a diatomic gas. They bond together in order to fill the outer shell of electrons. It is still an element.
Is xenon a compound element or mixture?
Xenon (Xe) is a element. It has atomic number 54 and is the fifth noble gas in the group. Xenon does not tend to form compounds due to its stability which can be attributed to its electronic configuration in which the outer shell are fully filled with electrons.

Why is the element from group 1 not as useful as its compound?
i think that they are not use fl because they only have one electrone on the outer shell
What is a compound word for shell?
shell

Why do noble gases not normally form compounds?
Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.
What is the first element that need a third shell?
It is sodium Chlorine is the first element that needs a third shell.
How are molecules of an element and a compound different?
Hydrogen symbol : H , and atomic number : 1 is an element . Whereas H2 is the hydrogen compound . The element may not be stable but molecule are always stable . When we see the molecular structure of hydrogen element , the outer most valence shell has one electron , which means hydrogen needs one more electron to fulfill its duplet . When the octate and duplet are fulfilled they are stable . In compound various element and molecules , bond to complete each others octate or duplet . Compound have certain bond . Eg electrovalent bond and covalent bond .
