atoms that have gained an electron are called ANIONS and they are much LARGER than their RESPECTIVE atoms as an ADDITIONAL atom occupies an outer orbital there is increased electron - electron REPULSION which pushes the electron further apart

amond to about 900 degrees C in the presence of air, DIAMOND will burn into CO2 But heat it to 1500 degrees C in the absence of air, it turns into graphite EXPLAINATIONDiamond is SP3 HYBRIDIZED & linked to 4 carbon atoms by single covalent bonds.It is REGARDED as 3-D polymer.It has very high M.P of 4200K & more energy is req. to break the bonds.In vaccum diamonds r stable upto 1500deg C but at 1800-2000 they r converted to graphite.HOPE THIS WILL HELP YOU

e the charged particle. You can say that ions are the charged ATOMS. They have EITHER positive, (+) or negative ( - ) charge on them. We know that the atom as a whole are neutral, that is, they have number of protons = number of electrons. If the ELECTRON is removed from the atom, then the number of electrons become less than the number of protons. Hence, the neutral atom becomes charged as the proton becomes GREATER in number than electron. Hence, it acquires a positive charge. These positive ions are called as cations. Example :- Na+ Now if electron is provided or acquired by the atom, than it becomes negatively charged as the number of electrons become greater than the number of protons. Since negative charge is greater in the atom, it becomes a negatively charged ION. These negatively charged ions are called as anionExample :- Cl-

cific heat of a body is defined as the quantity of heat required to raise the temperature of unit MASS of a body through one DEGREE Celsius.S=Q/m ΔTTo DETERMINE the specific heat of solids usually the method of mixtures is followed.In method of mixtures, specific heat of either a solid or a liquid is determined.The method of mixtures OBEYS the fundamental principle of calorimetry.Heat lost by hot BODIES= Heat gained by cold body

Al = (1.5) ≅ Be (1.5) Beryllium element  will has the SIMILAR  electronegativity of aluminium.  The electronegativity  of the element's in the power for an atom with a molecule to ATTRACT electron by the density itself. IT mainly DEPENDS on the factors which are particular for the atom of molecules. It will pulls the shared atom electron pair TOWARDS it.

commonly called silica (sand) . SiO2 is not a linear compound. It net like structure. That is one Si atom are bonded with 4 oxygen atoms and each oxygen atom are bonded with another Si atom.all bonds are sigma bond( single bond only)so SiO2 is sp3 hybridisation ( hybridisation is mixing of atomic orbital with different ENERGY ,shape, orientation to get atomic orbital with same energy ,shape,orientation) “Hybridisation can easily get in stectural formula ,that is number of sigma bond = number of atomic orbital hybridised CO2 is linear molecule with zero dipole moment ( due to linear structure) C and O Bond is double bond .in that double bond one is sigma and other is PI bond. hybridisation of CO2 is so Due to difference in hybridisation and structure SiO2 and CO2 are found in two defferent state.AND::Intermolecular FORCES. Silicon dioxide is really strange with its shape. You'd assume it to be linear like carbon dioxide but it holds a more tetrahedral orientation. This polarizes the molecule and helps them FORM complex chains of silicon dioxide. It's hard to find black and white information on this as many articles will contradict each other. But we do use silica as a polar surface for TLC and glass does have a slight attraction to water. So I GUESS that's the answer. Silicon dioxide is polar. Carbon dioxide is not.i hope it will helps you friend

CID: 24462 Chemical Names: Copper sulfate; 7758-98-7; Copper(II) sulfate; Cupric sulfate anhydrous; Copper sulphate; Copper(2+) sulfate   More... Molecular Formula: CuSO4 or CuO4S Molecular Weight: 159.602 g/mol InChI KEY: ARUVKPQLZAKDPS-UHFFFAOYSA-L Drug Information: Drug Indication  Therapeutic Uses  FDA UNII SAFETY Summary: Laboratory Chemical Safety Summary (LCSS) Copper sulfate is a sulfate salt of copper. It is a POTENT emetic and is used as an antidote for poisoning by phosphorus. It also can be used to prevent the growth of ALGAE. from MeSH Cupric sulfate is a salt created by treating cupric oxide with sulfuric acid. This forms as large, bright blue crystals containing five molecules of water (CuSO4∙5H2O) and is also known as _blue vitriol_. The anhydrous salt is created by heating the hydrate to 150 °C (300 °F). Cupric sulfate is used primarily for agricultural purposes, as a pesticide, germicide, feed additive, and soil additive. Some of its secondary uses are as a raw material in the preparation of other copper compounds, as a reagent in analytic chemistry, as an electrolyte for batteries and electroplating baths, and in medical practice as a locally applied fungicide, bactericide, and astringent [L1820]. Copper is an essential trace element and an important catalyst for heme synthesis and iron absorption. After zinc and iron, copper is the third most abundant trace element found in the human body. Copper is a noble metal and its properties include high thermal and electrical conductivity, low corrosion, alloying ability, and malleability. Copper is a component of intrauterine contraceptive devices (IUD) and the release of copper is necessary for their important contraceptive effects. The average daily intake of copper in the USA is approximately 1 mg Cu with the diet being a primary source [A32221]. Interestingly, the dysregulation of copper has been studied with a focus on neurodegenerative diseases, such as Wilson’s disease, Alzheimer’s disease, and Parkinson’s disease. Data from clinical observations of the neurotoxic effects of copper may provide the basis for future treatments affecting copper and its homeostasis [L1830]. from DrugBank CUPRIC SULFATE is a white or off-white solid. Melting point 200°C with decomposition. Non-combustible.

ivalent mass of the METAL is 12. It means 12 grams of the metal COMBINE with 8 grams of oxygen to GIVE 20 grams (12g+8g=20g) of the oxide. Hence, the equivalent mass of the metal oxide is 20.
