英文/音标中文/解释

1	chemistry symbols	化学符号
	Symbols that simplify the writing of the elements, formulas and chemical reactions. 简化元素、公式和化学反应书写的符号。
2	reaction direction	反作用方向
	A chemical reaction corresponds to the conversion of reactants in products and is obtained by the loss of one of the reactants. The arrow indicates the direction in which this irreversible reaction occurs. 化学反应相当于反应物在产物中的转化，并通过其中一种反应物的损失而获得。箭头指示不可逆反应发生的方向。
3	reversible reaction	可逆反应
	Chemical reaction that can occur in both directions; the products obtained (direct reaction) react between them to change back into the original reactants (inverse reaction). 双向发生的化学反应；得到的产物（直接反应）在它们之间发生反应，变回原来的反应物（逆反应）。
4	positive charge	阳电荷,正电荷
	Symbol that indicates a loss of electrons in an atom, which means the atom has a positive electric charge. The sodium atom, for example, forms a positive ion that is denoted as Na+. 表示原子中电子丢失的符号，表示原子带有正电荷。例如，钠原子形成一个正离子，表示为Na。
5	negative charge	带负电,负电荷
	Symbol that indicates a surplus of electrons in an atom, which means the atom has a negative electric charge. The chlorine atom, for example, forms a negative ion that is denoted as Cl. 表示原子中电子过剩的符号，表示原子带负电荷。例如，氯原子形成一个负离子，用Cl表示。
