is the property of an isolatedatom while oxidation STATE is calculated for an atom is PRESENT in a molecule i.e, in a BONDED state. 3.Valency of an element REMAINS thesame while its oxidation state may be different in different MOLECULES.

is POISON OUS

is INTENSIVE PROPERTY it DEPENDS UPON CONCENTRATION

is TRUE ANSWER

is true that radius decreases as we move from left to RIGHT in a PERIOD in the PERIODIC table. Fluorine has the smallest atomic radius. As we move to neon in the same period, the atomic radius increases as it has van DER waals radius and van der waals

lear metal carbonyls contain only one metal atom as the central atom. Except vanadium hexacarbonyl only metals with even order NUMBER such as chromium, iron, nickel, and their homologs build neutral MONONUCLEAR complexes. ... Carbon MONOXIDE has different BINDING MODES in metal carbonyls.

olecules are 10 POWER -3

has a valency (or FORMAL charge) of -2 if you calculate it carefully3 x (+1) + x = 1 (METHOD to calculate formal charge)3 + x = 1x = -2Hence no rule is violated

ne hole occurs during the Antarctic spring, from September to early DECEMBER, as STRONG westerly winds START to circulate around the continent and create an atmospheric container. Within this polar vortex, over 50 percent of the lower stratospheric OZONE is destroyed during the Antarctic spring.

e cation is exceptionally small it distorts the ELECTRON cloud of the ANION and at that time it has high polarizing power.In GROUP 1 lithium has high polarizing power

of CARBON DIOXIDE is PRODUCED.

. Equivalent of a SUBSTANCE implies the weight which CONSOLIDATES or DISPLACES 1 g of H2, 8 g O2 or 35.5 g of Cl2  In that way 1 g likeness O2 =8g  Weight of 1 mole of O2= 32g=32/8=4 equivalentThe mole, which is written as mol, is a SI unit which estimates the quantity of particles in a particular substance. One mole is equivalent to \(6.02214179 \times 10^{23}\) particles, or other basic units, for example, ATOMS.

ases do not become liquid when they are compressed at normal temperatures, even at very HIGH pressures. Commonexamples of these are oxygen, nitrogen, HELIUM and argon.

acid is present in our stomach because if more acid is secreted then we feel acidity and this acid HELPS us to digest the food.2) This answer is on OPTION 1)3) HCL

is #8 in the periodical table. FIRST electron shell can hold 2 ELECTRONS; SECOND, 8. Therefore, out of 8 electrons, 2 go to the first shell and 6 to the second; valence electrons are the ones on the OUTERMOST shell (there are some EXCEPTIONS, but they are much further down the table).

mical FORMULA of PHENOL is C6H5-OH.. This means it has a benzene ring in it. In benzene ring there in all 3 PI bonds and remaining 6 sigma bonds. OH group doesnt POSSES any pi bond but has 1 sigma bond between O & H. and 1 sigma bond is PRESENT between benzene ring and OH group.

electororrrrrr

he ATTACHMENT

Hydrogen SULPHIDE Explaination:Hydrogen Sulphide is expected to have a HIGHER boiling point as it is formed by ionic BONDS whaeras water is formed by covalent bonds. Ionic COMPOUNDS have a higher boiling point as compared to Covalent Compounds. This is because the bonds between the ATOMS of covalent bonds are less stronger than that of ionic bonds. Ionic Bonds, hence have comparatively higher melting and boiling points.
