Which element has the second-highest electronegativity? ___. Electronegativity: The electronegativity of an atom of an element is a measure of the force with which the atom pulls on the shared electrons in a covalent bond. The index is important to investigate t...
For the elements below, indicate how each element's valence electrons act in a chemical reaction (loses electrons, gains electrons, can either lose or gain electrons, or is generally unreactive): H, K Which of the following elements will for...
Where is neon found? Neon is a very rare element on Earth. It is found invery small traces in both the Earth's atmosphere and the Earth's crust. It can be produced commercially from liquid air through a process called fractional distillation. ...
Which element is most likely to accept electrons? Thus,nonmetalshave a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity. For example, nonmetals like the elements in the halogens series in Group 17 have a higher elec...
Because in the debris combines [4] and so on acid, alkali, aerosol material, heavy metal element, dressing medicament and including curing mineral, the debris meets the rainfall to be extremely easy to wash away periphery, along with the rain water inflow farmland, the rivers, the pollution ...
Which element has the highest ionization energy? Explain the answer. Be, I, or Te. Which of calcium or sodium has a higher ionization energy? Which has a higher (more positive) first ionization energy, K or O? Which has the lower first ionization energy: N or F? Explain...
is an alkylene group, R3 and R4 are polyatomic groups, and when G1 is a substituent defined for Nu, an adjacent R3 or R4 can be the group: ##EQU7## X1 is a ballasting group of sufficient size to render said compound immobile in an alkali-permeable layer of the photographic element ...
