The bolded statements are true:
1. The octet rule can be violated.
2. Atoms are most stable when their atomic number is divisible by 8.
3. All free atoms contribute eight valence electrons to form molecules.
4. Only the oxygen atom can have an expandable octet.
5. In order to obey the octet rule, some atoms have to share more than one pair of electrons.
What else can I help you with?
Is NH3 an exception to the octet rule?
NH3 is not an exception to the octet rule. Nitrogen (N) in NH3 has a total of 8 valence electrons (5 from nitrogen and 3 from hydrogen), fulfilling the octet rule. Nitrogen has 3 bonded pairs and 1 lone pair of electrons, following the octet rule.
Can iodine exceed the octet rule and have an expanded octet?
Yes, iodine can exceed the octet rule and have an expanded octet due to its ability to accommodate more than eight electrons in its valence shell.
Which doesn't violate the octet rule sf4 krf2 cf4 xef4 icl4-?
CF4 and XeF4 do not violate the octet rule. In CF4, carbon forms four covalent bonds with fluorine, fulfilling the octet rule. In XeF4, xenon forms four covalent bonds with fluorine and has two lone pairs, also satisfying the octet rule.
Does BeH2 violate the octet rule?
The octet rule only applies to elements that are heavy enough to have reached the second shell of electrons. In the first shell, the octet rule does not apply because the first shell is completed with only two electrons, not eight. So no, the octet rule does not apply to beryllium hydride.
Do Cu plus and Cu2 plus plus violate the octet rule?
Yes, both Cu+ and Cu2+ violate the octet rule. Copper (Cu) is an exception to the octet rule due to its electron configuration, which allows it to have a partially filled d orbital. This leads to Cu forming compounds where it does not achieve a full octet of electrons.
The Octet Rule states that many chemical compounds tend to form bounds. True or False?
True. The Octet Rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons, making them more stable.
Give example of octet rule?
Az important rule: any octet has to have eight parts, otherwise it is not an octet.
Is it true that dying declarations and spontaneous statements are considered exceptions to the hearsay rule?
True
In which bonding patterns does X obey the octet rule?
no it does not follow octet rule
Will any of the chlorine oxides obey the octet rule?
No chlorine oxides will obey the octet rule.
Is NH3 an exception to the octet rule?
NH3 is not an exception to the octet rule. Nitrogen (N) in NH3 has a total of 8 valence electrons (5 from nitrogen and 3 from hydrogen), fulfilling the octet rule. Nitrogen has 3 bonded pairs and 1 lone pair of electrons, following the octet rule.
Which of the atoms don't always obey the octet rule H O Br?
Hydrogen is the atom that doesn't always obey the octet rule. It only needs 2 electrons to have a full outer shell, rather than the 8 electrons typically required by the octet rule. Oxygen and bromine usually follow the octet rule.
Can iodine exceed the octet rule and have an expanded octet?
Yes, iodine can exceed the octet rule and have an expanded octet due to its ability to accommodate more than eight electrons in its valence shell.
What is significant of octet rule?
The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
What rule do the nonmetal atoms follow?
octet rule
