bond energy (in kJ/mol)
F-F:158
Cl-Cl: 244
Hence, in order of decreasing bond strength:
Cl-Cl => => (F-F) =>
Fluorine is an anomaly.
Bond strength decreases from chlorine to iodine as down the group, the atomic size becomes larger and thus the valence electron orbitals become more diffused, causing the overlap of orbitals to become less effective. Therefore the halogen-halogen bond becomes weaker.
Fluorine is an exception due to its extremely small size. The F-F bond length is so short that the lone pairs of electrons on the fluorine atoms repel each other and weakens the F-F bond.
I hope that answers your question.
No, the N-F bond is stronger than an F-F bond
It generally means "and following". It is used for example in citations and reference literature when the reference is to "page 15 and the following pages", then the annotation is ".... p 15 ff."
To draw the Lewis structure for C2H4, the total number of valence electrons must be known. Carbon has 4 and hydrogen has 1, making a grand total of 12 e- (4*2 + 4*1). All electrons are shared within bonds in this compound. Carbon and Carbon are double bonded to each other, with each carbon having two hydrogens attached. Each element in this arrangement has a full outer shell. Hydrogen has 2 and each carbon has 8.
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
Simply divide by the number that signifies moles of any thing; Avogadro's number. 3.4 X 10^23/6.022 X 10^23 = 0.56 moles of H2SO4
By nature electrons are charged particles (with a -1 charge). Also there's an established relationship between electricity, which involves the flow of electrons, and magnetism, known as electromagnetism. Ampere's right-hand rule suggests the magnetic field moves in a corkscrew direction perpendicularly in reference to the direction of the flow of electrons (electrical current).
No, "ff" is not considered a true word in English. It is typically used as an acronym for various phrases rather than standing alone as a word with a specific meaning.

That's called the "MAC address" or "Hardware address". It's a unique set of numbers assigned to a network device. Anything that access the internet whether phones, wireless cards, computers, etc, all have a MAC address. The address with all one's (FF-FF-FF-FF-FF-FF) is the broadcast address. All devices on the physical segment will see and respond to a message with that destination.
The offspring from an FF X ff cross will all have the genotype Ff.This is because they receive one allele from each parent, and in this case they can only receive an F from the FF parent and an f from the ff parent.

In IPv6 addresses the number FF often appears What is the decimal value of FF?
In my opinion its ff 7 or ff 13 or ff versus 13
Jesus hates you...ff.
Ff stands for "fullscreen," indicating that the DVD content is presented in a fullscreen aspect ratio (4:3) rather than widescreen (16:9).
