WebMar 24, 2024 · Explanation: Number of protons always equal number of electron, but that's the case with a neutral atom. A neutral atom is an atom of any element that has no electric charge over it. This implies that it has same number of protons and electrons in it. It means it has same amount of positive and negative charge, which cancel each other, and the ... WebAug 1, 2024 · If an atom has the same number of protons and electrons, it is electronically neutral. However, if the total number of electrons does not equal the number of protons, the atom has a net electrical charge. Any atom or molecule with a net charge, either positive or negative, is known as an ion.

WebThe chemistry of the atom is associated with its electron distribution. The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom. This is known as the atomic number, Z. The removal or addition of electrons to a neutral atom creates ions that have a net negative or positive charge. WebMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to … The electrons in an atom are arranged in shells that surround the nucleus, with … Valence electrons are the electrons in the outermost shell, or energy level, of an … did elliot rodger livestream his attack
