How does calcium obey the octet rule when reacting to for compounds?
Calcium has 2 valence electrons and tends to lose these electrons to achieve a stable electron configuration with a full outer shell. When reacting to form compounds, calcium typically loses 2 electrons, resulting in a stable 2+ cation. This allows calcium to achieve an electron configuration similar to a noble gas, following the octet rule by having a full outer shell of 8 electrons.
Will calcium form an ionic bond or a covalent bond?
Calcium typically forms ionic bonds. As a group 2 metal, calcium readily donates its two valence electrons to achieve a stable octet configuration, forming the Ca2+ cation. This cation then forms ionic bonds with other ions or compounds.
How can xenon achieve stable octet?
Xenon can achieve a stable octet by forming compounds with elements that can share their electrons with xenon. For example, xenon can form compounds with fluorine, chlorine, or oxygen where xenon acts as the central atom and bonds with these more electronegative elements to complete its octet.
Can Li and Ca form ionic compounds?
Yes, lithium (Li) and calcium (Ca) can form ionic compounds. Lithium has a +1 charge, and calcium has a +2 charge, so they can combine to form compounds like lithium chloride (LiCl) or calcium fluoride (CaF2) through ionic bonding.
Does BCl3 follow the octet rule?
No, BCl3 does not follow the octet rule as boron only has 6 valence electrons in this molecule. Boron can form stable compounds with less than an octet due to its electron deficiency.
How many what elements can form compound with an expanded octet Pb Kr Si B?
Among the elements listed, lead (Pb) can form compounds with an expanded octet, as it is a heavier element that can utilize d-orbitals for bonding. Krypton (Kr) is a noble gas and typically does not form compounds due to its complete octet. Silicon (Si) and boron (B) usually follow the octet rule, although boron can sometimes form compounds with less than an octet. Therefore, only lead can form compounds with an expanded octet from the elements provided.

What compounds form stalactites and stalagmites and stalagmites?
Calcium Carbonate
What is sodium and calcium in form ionic compounds?
Sodium and calcium form the cations Na+ and Ca(2+).

Does uranium have an octet?
Uranium typically forms compounds where it does not have an octet due to its ability to expand its valence shell beyond eight electrons. Uranium can often exceed the octet rule in its bonding arrangements.
Covalent calcium compounds?
Calcium cannot form a covalent compound because it is a metal, covalent compounds are formed only from non-metals.
Which elements can combine with boron to form octect?
Boron typically forms compounds by sharing electrons, rather than obtaining a full octet. It can form compounds with elements such as hydrogen and fluorine, but it often displays unique bonding patterns due to its electron deficiency.
Does BCl3 follow the octet rule?
No, BCl3 does not follow the octet rule as boron only has 6 valence electrons in this molecule. Boron can form stable compounds with less than an octet due to its electron deficiency.
When compounds like to have 8 electrons in their outter shell what does that mean?
There is a general tendency to form an octet, to have a stable structure.
