The easiest way to count atoms: 1. Write down all of the symbols for all of the elements present in the formula 2. If there is a coefficient, write this number next to each of the symbols 3. Multiply the coefficient by the subscripts of each of the elements present in the formula Let...
The chemical formula of a compound is X2Y3. If there are 12 atoms of Y, how many atoms of X are there? A. 6 atoms B. 8 atoms C. 10 atoms D. 12 atoms 相关知识点: 试题来源: 解析 B。由化学式 X2Y3 可知,X 和 Y 的原子个数比为 2:3,Y 有 12 个原子,设 X 有 x 个原子...
To determine the mass of a compound, you count the atoms in the compound by looking at its chemical formula. Look up the masses of each of the atoms that constitute the molecule in the periodic table, add up these masses, and you'll have the mass of the molecule in AMU. This is als...
In chemistry, a compound's valence number is the number of bonds formed by the electrons in the last (outer) shell (called valence electrons) of atoms to other atoms' valence electrons. The octet rule (the tendency of an atom to seek stability by filling its outer shell with eight electro...
conducts electricity more than an insulator, such as glass, but less than a pure conductor, such ascopperor aluminum. Their conductivity and other properties can be altered with the introduction of impurities, called doping, to meet the specific needs of the electronic component in which it ...
compound. Information regarding theactualnumber of atoms of an element present in a compound is provided by its molecular formula. To determine the molecular formula of a compound, multiply the subscripts of each element in the empirical formula by the ratio of molecular weight to empirical formula...
Some of the energy from the X-ray photon works to separate the electron from the atom, and the rest sends the electron flying through space. 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 ...
