What term indicates how strongly an atom attracts the electrons in a chemical bond?
Electronegativity, symbol χ (the Greek letter chi), is a chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself and thus the tendency to form negative ions.[1] An atom's electronegativity is affected by both its atomic number and the distance that its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it.Taken from Wikipedia entry titled Electronegativity.
3 The label on a bottle indicates that the substance inside has a pH of 13 This tells you that the substance is A neutral B strongly acidic C mildly basic D strongly basic?
D
What valence electrons has in rubidium?
The Rubidium valance shell is a radio active substance
What happens to the polarity of oxygen atoms as they transform from molecular oxygen into water molecules?
In the bond in molecular oxygen, the electrons are pulled equally towards each element, as they are the same element and so have the same electronegativity. In water, however, the bonds are between hydrogen and oxygen. The nucleus of oxygen has eight times the charge of the nucleus of hydrogen, and so attracts the electrons more strongly than hydrogen does. It does not attract eight times as strongly as hydrogen as the extra electron shell repels the electrons in the bond more than hydrogen's nonexistent shells (its only electron is in the bond). It can therefore be said that oxygen is more electronegative than hydrogen. As the oxygen attracts the electrons more strongly than the hydrogen, it gains a partially negative charge. Similarly, the hydrogen gains a partially positive charge. This polarity is responsible for the interesting properties of water, including its ability to stay liquid at room temperature, its low density as a solid and its ability to climb up a narrow capillary tube without any force applied to it.
An atom in a polar covalent bond that attracts electrons more strongly is said to have greater what?
Electronegativity ~ "a measure of n atom's ability to attract a shared pair of electrons within a covalent bond"
Why is P680 of photosystem II said to be the strongest biological oxidizing agent?
This molecule results from the transfer of an electron to the primary electron acceptor of photosystem II and strongly attracts another electron.

What is the meaning of cynosure?
something that strongly attracts attention by its brilliance, interest, etc.
What prevent an element in a covalent compound from taking away another element valence electron?
This all has to do with the difference in electronegativity between the two atoms. The electronegativity is a measure of how strongly an atom attracts electrons. If they both attract electrons with about the same affinity (not a big difference in electronegativity), then you have a covalent bond, and they SHARE the electron(s) equally or almost equally.
What atom attracts electrons less strongly than the sulfur atom when combined?
oxygen and carbon -the gamdecbdvcjd
Why does the oxygen in a water molecule have a negative charge?
Oxygen attracts electrons more strongly than hydrogen does.
Why a lithium atom holds its outer electrons more strongly?
Neither of these metals hold onto their outer electron (singular, as they are alkali metals) very strongly. Relatively speaking though, lithium holds onto its outer-most electron more strongly than Sodium does.
Is expanding universe accurate?
All the available evidence strongly indicates that the Universe is, indeed, expanding.
Which element consists of atoms that's most strongly attract electrons of other atoms?
The element that attracts electrons the most would be Fluorine
How does the arrangement of alkali earth metals make them very reactive?
Alkalis have one electron in their valency shells. They can "lose" this electron easily, forming a cation which is strongly reactive.

D
Why are lithium and sodium in the same group in the periodic table?
Elements that are in the same group of the periodic table have the same number of electrons in their outer energy level. In the case of lithium and sodium, they each have one electron in their farthest shell.
