WebLithium is a chemical element with atomic number 3 which means there are 3 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. WebAn atom has 33 protons, 41 neutrons, and 36 electrons. What is a correct description of the atom? answer choices an ion with a net charge of 3- an atom with an atomic mass of 36 an atom with an atomic mass of 33 an ion with a net charge of 3+ Question 6 300 seconds Q. Malleability is a physical property of matter.

WebIn ethyl chloride, the Cl atom is the most electronegative atom. It pulls electron density from the C atom, so it becomes δ⁻ and the C atom becomes δ⁺. Ethanol is a nucleophile (N) because the O atom has lone pairs and a δ⁻ charge. Ethyl chloride is an electrophile (E) because the δ⁺ C atom attracts the negative charge in other ...
