An element that has the electron configuration (Ne)3s2 is in the group: a. 2. b. 5. Determine the number of (a) electrons, (b) protons, and (c) neutrons in iron (2656 Fe). What is the ratio of the number of electrons for each atom of lead over one atom of aluminum?
I like the 3d element of building up to potentially score more points. The first few rounds we didn't spend stone to get different tiles, but as our towns took shape and we grasped the game we started to spend.I won, 94-73. Give GeekGold More Actions Add Comment Added Jan 1, ...

The mono- prefix is often dropped for the second-named element if it is the only common compound the elements form. Thus referring to H2S as hydrogen monosulfide is much rarer than the name hydrogen sulfide. However, since carbon and oxygen can form several compounds (carbon monoxide, carbon ...

What is the molar mass, in grams, of a mole of an element equal to? What is the molar mass of C12H22O11? The density of a gas is 2.436 g/l at 27.0C and 745 torr. What is its molar mass? What is the relationship between the density of a gas and its molar mass? What is the...
What is the molar mass of glycerin? What is the molar mass of magnesium sulfate? What is the molar mass of CaF2? What is the molar mass, in grams, of a mole of an element equal to? What is the mass of one mole of H2?
What is the molar mass of Barium? Atomic Mass and Molar Mass The periodic table lists the atomic mass and molar mass of each element. The values are the same, but their units are different. Atomic mass has the units atomic-mass-units, or AMU. Molar mass is the mass of one mole of ...
What comes to mind when people think of the word hydrogen? The single electron element on the periodic table? The hydrogen bomb? Or even H20? Yet there is another use for this wondrous gas, fuel cell technology.Totse Com
(Li) and oxygen combine to create lithium oxide (Li2O). Sometimes, a new compound might form when an element is exposed to an existing compound. For example, when pure elemental sodium (Na) is submerged into liquid water (H2O), a reaction occurs, resulting in the formation of sodium ...
