Atoms with a low ionization energy give up their outer valence electrons with ease true or false

umka2103 [35]

Answer: The given statement is true.

Explanation: Ionization energy is defined as the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.

General equation of ionization energy is given by:

$X(g)\rightarrow X^+(g)+e^-$

If the outermost electron is loosely bound to the nucleus which means that the electron can be easily removed form an atom, it will require less amount of ionization energy.

And if the outermost electron is tightly bound to the nucleus which means that the electron cannot be removed easily from an atom. And hence, it will require more ionization energy.

Hence, the given statement is true.

Prokaryotic cells have a cell wall surrounding their cell membrane .The Prokaryotic cells don't have a well defined nucleus .The genetic material of the cell is basically naked and not enveloped by the Nuclear membrane .
Eukaryotic cells don't have a cell wall surrounding their cell membrane. The Eukaryotic cells have a well organised nucleus .The genetic material of the cell is surrounded by nuclear membrane or nuclear envelope.
Both Eukaryotic and prokaryotic cells have DNA.Both have a plasma membrane or cell membrane.

mamaluj [8]

The outer periphery of the inter-vertebral disk is composed of strong fibrous tissue called the Annulus fibrosus. This is a tough circular exterior of the inter-vertebral disc that surrounds the soft inner core, the nucleus pulposus. The outer portion is composed of a ring of ligament fibers that encases the inner core of the disc and securely connects the spinal vertebrae above and below the disc.
