c- NH_3 and NH_3. d- NH_3 and CH_4. e- CH_4 and CH_4. What is the electronegativity for an ionic bond? Given the electronegativity values below, which of the following covalent single bonds is the most polar? Element Electronegativity H 2.1 C 2.5 N 3.0 O 3.5 (a) C-H (b)...
Diffraction refers to the phenomena of slight bending of light as it encounters an obstacle or a slit or as it passes around the edge of an object. In diffraction, the amount by which light is bent depends on the relative size of the wavelength of the light to the opening of aperture. ...
Charli XCX‘s music video performance ofYou’re The Oneis obviously a love song from the perspective of a woman finally realizing she’s found “the one” (i.e., the love of her life). But I would like to indulge your creativity to interpret the lyrics (reflected below) a bit differe...
Anelementis a substance that cannot be separated into simpler substances by chemical means. An element consists of anatomwith a unique combination ofprotons,neutrons, andelectrons. For example, the element hydrogen has one proton, one neutron, and one electron. We cannot use chemical methods to b...
What is the element with the following electron configuration? 1s22s22p63s23p64s23d1 What atom is indicated by the following electron configuration. 1s^22s^12p^1 ? What is the electron configuration for the transition metal ion in the following compound? [Co(H_2O)_2(NH_2CH_2CH_2NH_2)_...
Nitrogen is an essential element for living organisms as it’s needed to make proteins for growth and repair and other biological functions. Nitrogen moves through the air, soil and living organisms ( plants, animals and bacteria ) in a process called theNitrogen Cycle. ...

An element that distinguishes NICE from most other agencies is the explicit statement of a cost-effectiveness threshold, in terms of cost per quality-adjusted life-year (QALY) gained (£20,000–30,000), to classify interventions as good value for money. Cancer is a leading cause of ...
What is the other element that is mostly found in the organic compounds after carbon?Chemical Compounds:The 118 elements known to contemporary chemistry are capable of bonding in various forms to produce a host of compounds. Broadly speaking, we may classify compounds as ...
