look up its name in the table under the Resources section below. Each name has a symbol that corresponds to it. Sulfate, for example, is SO4 -2 (with the -2 as a superscript and the 4 as a subscript, since there are 4 oxygen atoms). ...
How many Au atoms will react with 996 molecules of HCl in the following equation? Au(s) + 3HNO3(aq) + 4HCl(aq) arrow HAuCl4(aq) + 3NO2(g) + 3H2O(l) According to the following balanced reaction, ho...
Determine the total number of valence electrons in each of the following: a) COCl2 b) N2O c) ClO2- d) SeCl2 e) PBr3 How many valence electrons does Ne have? How many valence electrons does terbium (Tb) have? How many valence electrons are in each of the following atoms? a. Mg b....
Atomic number:The number of protons in an atom's nucleus is referred to as the atomic number of that element. The number of protons defines what element it is and determines its chemical behavior. For example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalw...
The most expensive natural element isfrancium. Although francium occurs naturally, it decays so quickly that it cannot be collected for use. Only a few atoms of francium have been produced commercially, so if you wanted to produce 100 grams of francium, you could expect to pay a few billion...
An atom has the following electron configuration. 1s^22s^22p^63s^23p^4 How many valence electrons does this atom have? How many valence electrons are in each of the following atoms? a. Mg b. C c. Br d. Cs What are valance electrons? How many val...
How many electrons are gained by atoms of Br to obtain a stable electron configuration? All the 4f orbitals can collectively hold how many electrons? How many valence electrons do the noble gases have? a. 1 b. 2 c. 8 d. 10 How many unpaired electrons are in the fluorine atom? How ma...
Nitrogen trichloride is more reactive. This primarily based on 2 factors: the size of the atoms and the electronegativity of the atom. Fluorine has an electronegativity of roughly 4, while chlorine has an electronegativity of roughly 3. In layman's terms, this means fluorine holds onto electrons...
A larger atom is more likely to absorb an X-ray photon in this way, because larger atoms have greater energy differences between orbitals -- the energy level more closely matches the energy of the photon. Smaller atoms, where the electron orbitals are separated by relatively low jumps in ...
