Nucleus in a sentence

An electron farther from the nucleus has higher potential energy than an electron closer to the nucleus, thus it becomes less bound to the nucleus, since its potential energy is negative and inversely dependent on its distance from the nucleus.

In humans, when an egg cell is fertilized by a sperm, the egg nucleus and sperm nucleus each contribute equally to the genetic makeup of the zygote nucleus.

Nucleolus main An electron micrograph of a cell nucleus, showing the darkly stained nucleolus 3D rendering of nucleus with location of nucleolus The nucleolus is a discrete densely stained structure found in the nucleus.

The nucleus parity will be a product of theirs, while the nucleus spin will be one of the possible results of the sum of their angular momenta (with other possible results being excited states of the nucleus).

The triplet is : and thus consists of three types of nuclei, which are supposed to be symmetric: a deuterium nucleus (actually a highly excited state of it), a nucleus with two protons, and a nucleus with two neutrons.

The tritium nucleus, containing one proton and two neutrons, has the same charge as the nucleus of ordinary hydrogen, and it experiences the same electrostatic repulsive force when brought close to another atomic nucleus.

They emerge from the nucleus as cones of dust and gas, and then are curved into broader fan-like structures by the rotation of the nucleus.

The fertilized nucleus (known as the pronucleus) of the donor egg is destroyed and replaced with the fertilized nucleus of the maternal egg, which has the DNA of the mother and the father.

A helium nucleus was presumed to be composed of four protons plus two "nuclear electrons" (electrons bound inside the nucleus) to cancel two of the charges.

A hydrogen nucleus is a single proton, so simultaneous nuclear interactions, which would occur within a heavier nucleus, don't need to be considered for the detection experiment.

All other orbitals (p, d, f, etc.) have angular momentum, and thus avoid the nucleus (having a wave node at the nucleus).

Although small molecules can enter the nucleus without regulation, citation macromolecules such as RNA and proteins require association karyopherins called importins to enter the nucleus and exportins to exit.

A nucleus was not like a brittle solid that can be cleaved or broken; George Gamow had suggested early on, and Bohr had given good arguments that a nucleus was much more like a liquid drop.

A schematic of the nucleus of an atom indicating radiation, the emission of a fast electron from the nucleus (the accompanying antineutrino is omitted).

As the nuclear charge of the nucleus increases across the period, the atomic radius decreases and the electron cloud becomes closer towards the nucleus.

At the other end of the periodic table, a nucleus of gold with a mass 197 times that of hydrogen, was thought to contain 118 nuclear electrons in the nucleus to give it a residual charge of + 79, consistent with its atomic number.

Cellular changes The nucleus changes in necrosis, and characteristics of this change are determined by manner in which its DNA breaks down: * Karyolysis: the chromatin of the nucleus fades due to the loss of the DNA by degradation.

Consider an electron of charge - and an atomic nucleus with charge +Ze, where Z is the number of protons in the nucleus.

Every atom is composed of a nucleus and one or more electrons bound to the nucleus.

Explanation Deuterium is an isotope of hydrogen whose nucleus comprises both a neutron and a proton ; the nucleus of a protium (normal hydrogen) atom consists of just a proton.
