Copper has an atomic number of 29 and a mass number of 64. what would result if an uncharged copper atom lost two electrons?
nikklg [1K]

The atomic mass of an element is the number of times of an atom of that element is  heavier than an atom of carbon taken as 12. In simpler way, atomic mass is number of protons present in  nucleus of an atom, which is a characteristic of an chemical element and is determines place of the element in the periodic table.  Mass number is total number of protons and neutrons. If an uncharged atom looses electron from its outermost shell, it becomes cation, which is positively charged species. Atomic number and mass number do not change if electron goes out of an atom.

Uncharged copper after loosing two electrons is converted to Cu^{2+} which can be represented as follows:

Cu_{29} ^{64}→Cu^{2+}

What is the empirical formula of a compound composed of 30.5 g potassium (k) and 6.24 g oxygen (o)?
VLD [36.1K]
K5O2

convert grams to moles, divide both by the smallest mole mass, multiply that until hole.

30.5 g K ÷ 39.10 = .78 mol
6.24 g O ÷ 16 = .39 mol
.78 mol ÷ .39 mol = 2.5
.39 mol ÷ .39 mol = 1
2.5 x 2 = 5
1 x 2 = 2
K5O2
