One lone pair and three bonding chlorine pairs. General shape is tetrahedral and it's a trigonal pyramidal.
It has 4 bonding pairs and no lone pairs so it has a tetrahedral shape.
In PCl3 there are three bonds to the central atom (P) and one lone pair.. This can be worked out as follows. P has 5 valence electrons, shares three electrons with the chorine atoms (1 each) leaving 2 electrons on the P as a lone pair. In VSEPR theory this is an AX3E compound like ammonia.
pairs of chromosomes in the human something i think
a DNA strand can have many different types of sequences but, T (thymine) always pairs with A (adenine) and C (cytosine) always pairs with G (guanine). think of your DNA strand as a ladder. every single ladder in exactly the same in your body. the two collunms of the DNA are the strongest parts of the whole strand. the collunms are made up of deoxyribose (sugar)(D) and a phosphate group (P)the rungs of the DNA (ladder) are the T, A, G, and C. they always pair with the same one but can be mixed up. EX: P P D GC D P P D TA D P P D AT D P P D CG D P P D GC D P P this is the DNA strand flatened out. the rungs can be in any order but have to be paired up with the same one. A & T, G & C

3 Iodine atoms, each with 3 pais of electrons (6 electrons), around a Phosphorus atom with 1 lone pair of electrons (2 electrons).

In icl3 central atom is iodine and its valency is 7 out of 7 electrons 3 electrons are in chemical bonding so 2 lone pairs are there. Hybridization = number of sigma bonds + number of lone pairs = 3 sigma bonds + 2 lone pairs = 5 = sp3d ( 1 s + 3 P + 1 d = 5 ).
Yes it is. (because of the lone pairs on N)

Boron is sp2 hybridised with an empty p orbital. Both chlorine and iodine have lone electron pairs of suitable symmetry to form a partial pi bond with the empty orbital of boron. This partial pi bond effect is stronger and more significant in BCl3 because there is a better energy match between the empty p of boron (LUMO) and the lone pairs of Cl (HOMO) than between boron p and the lone pairs of iodine. As a Lewis acid, boron takes an electron pair into its empty p orbital. In BCl3, the significant pi bond means that this p orbital is less electron deficient and therefore hinders the ability of the p orbital to accept an electron pair, so it is a weaker acid than BI3. Maybe consult a textbook or website for a picture to help you visualise Boron in sp2 hybridised state.
A prime number, P, has only two factor pairs: (1, P) and (P, 1).
