an atom is zero. This is because the number of protons is equal to the number of electrons. If an atom acquires electrons, it gains a negative charge which is equal to the number of electrons it has received. If an atom loses electrons, it will get the same num...
Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen). The peri...
In a normal atom, the number of protons is equal to the number of electrons in it. So, we can say that, “The atomic number of an element is equal to the number of electrons in a neutral atom of that element”. The atomic number of an element \(=\) Number of electrons in one ...
