For the first electron around the nucleus, the effective nuclear charge equals the nuclear charge: Zeff=ZZ_\text{eff} = ZZeff=Z. This is because a complete shell has been added below it (and according to Slater's rules, the contribution to the shielding is higher), increasing the distance from the nucleus. Can someone explain that or link to a video that better explains it? For every added electron sharing the same orbital or occupying lower energy orbitals, the negative charge of those particles adds a repulsive component, which contributes to the shielding of the nucleus' electrostatic interaction. We will explain various types of nuclear reactions as well as how nuclear energy (which is produced in abundance during nuclear reactions) is used in industry. The gamma dose rate calculator
Instead, there are multiple nuclear equations US-Russia, US-China, US-North Korea, India-Pakistan, India-China, but nothing is stand-alone. - [Voiceover] Let's look at three types of radioactive decay, and we'll start with alpha decay.
