WebA nucleophile is a species that is strongly attracted to a region of positive charge on a carbon atom in another molecule. In NH₃, N is more electronegative than H, so the N atom has a partial negative (δ⁻) charge. ... (N) because the O atom has lone pairs and a δ⁻ charge. Ethyl chloride is an electrophile (E) because the δ⁺ C atom ... WebJun 22, 2014 · Question #e4333. An excited state is an energy level of an atom, ion, or molecule in which an electron is at a higher energy level than its ground state. An electron is normally in its ground state, the lowest energy state available. After absorbing energy, it may jump from the ground state to a higher energy level, called an excited state.

WebThe I-129/I-127 atom ratios in rabbits collected on the INEL site were larger than ratios in rabbits from a control area. Maximum I-129/I-127 atom ratios (9.1 x 10-4) occurred near the Idaho Chemical Processing Plant (ICPP). Based on rabbit thyroid concentrations, the I-129 appeared to be deposited primarily in the direction of the predominant ... WebAnswer (1 of 12): The hybridization of the nitrogen atom in the compound NH4+ is sp3. In chemistry, hybridization refers to the mixing of atomic orbitals on a central atom to form a set of new, hybrid orbitals. These hybrid orbitals have different shapes and energies, and they are used to form c...
WebThe three species NO 2+, NO 2 and NO 2-all have a central N atom. The O-N-O bond angles in the three species are 180, 134 and 115 respectively. Explain this variation in bond angles … WebN 2 + O 2 N 2 O 5 (unbalanced) Though nitrogen is balanced, changes in coefficients are needed to balance the number of oxygen atoms. To balance the number of oxygen atoms, a reasonable first attempt would be to change the coefficients for the O 2 and N 2 O 5 to integers that will yield 10 O atoms (the least common multiple for the O atom ...
