charged (non-charged) neutrons are found in the nucleus Negatively charged electrons are located orbiting the nucleus in shells. They stay in orbit because the electrons are attracted to the protons 2: The Element Introduction An element is a singular type of atom‚ like candy in a candy shop If there is an atom that has 8 protons and 8 electrons‚ then it is an oxygen element. If it has 1 proton and 1 electron‚ then it is a hydrogen element 3: Molecules Introduction A molecule

Explain. a) NF3: 5 + (7*3) = 26 b) PCl2F3: 5 + (7*2) + (7*3) = 40 c) SF4: 6 + (7 *4) = 24 d) SCl2: 6 + (7*2) = 20 The answer is “d” because it does not have eight valence electrons. 64) Explain why each electron structure is incorrect.

the ability to "remember" the magnetic fields they have been subjected to. An atom consists of a number of negatively charged electrons‚ orbiting around a positively charged nucleus. These electrons also possess a quantity known as spin‚ which is roughly analogous to a spinning top. The combination of orbital and spin motions is called the angular momentum of the electron. Angular momentum is perhaps most easily understood in the case of the Earth: The earth spins about a central axis‚ which means

They name for these beta rays was soon replaced by the name electron. The English physicist by the name of JJ Thomson‚ discovered the electron in 1897. He was certain that every atom consisted of electrons. He deduced that since an atom contains a neutral charge and consists of negative electrons‚ there must be some other positively charged material within the atom to balance out the negatively charged electrons. He realized that the electrons alone could not account for the mass of one atom due to

sparks (electrons being released) more rapidly. Since light was predominately now thought to just be a wave‚ three main objections were raised in regard to Hertz’s observation of this now-called photoelectric effect. In 1914‚ Robert Millikan noticed that there was a cutoff frequency‚ ‚ at which no more electrons are shot out of the conducting electrodes (this work won him the 1923 Nobel Prize). Other experiments at the time showed that the maximum kinetic energy of the fasted ejected electron‚ ‚ was

Germanium and silicon are two well-known semiconductors. 1.2 Atoms and elements Ordinary matter is made up of protons‚ neutrons‚ and electrons and is composed of atoms. An atom consists of a tiny nucleus made up of protons and neutrons‚ on the order of 20‚000 times smaller than the size of the atom. The outer part of the atom consists of a number of electrons
