When cells or organisms maintain a stable internal state in a changing environment is called?

Answer:

Atoms are electrically neutral because the number of protons, which carry a 1+ charge, in the nucleus of an atom is equal to the number of electrons, which carry a 1- charge, in the atom. The result is that the total positive charge of the protons cancels out the total negative charge of the electrons so that the net charge of the atom is zero. Most atoms, however, can either gain or lose electrons; when they do so, the number of electrons becomes different from the number of protons in the nucleus. The resulting charged species is called an ion.

Cations and anions

When a neutral atom loses one or more electrons, the total number of electrons decreases while the number of protons in the nucleus remains the same. The result is that the atom becomes a cation—an ion with a net positive charge.

The opposite process can also occur. When a neutral atom gains one or more electrons, the number of electrons increases while the number of protons in the nucleus remains the same. The result is that the atom becomes an anion—an ion with a net negative charge. We can illustrate this by examining some very simple cations and anions, those formed when a single hydrogen atom loses or gains an electron.

Note: Hydrogen is actually somewhat unusual in that it readily forms both cations and anions. Most elements much prefer to form only one or the other. In terms of its electron configuration, can you explain why hydrogen can form both cations and anions? Feel free to post in the comments at the end of the article!

The statement that is not correct here is two or more electrons in an atom can have the same set of quantum numbers. The correct option is a.

To describe the location of an electron in an associated atom, we use a series of specific numbers known as quantum numbers.

Quantum numbers describe the properties of atomic orbitals and the electrons within them. The state of an electron in an atom or ion is described by four quantum numbers.

The primary quantum number, denoted by n, represents the electron's primary energy level. Energy levels are fixed distances from an atom's nucleus.

According to the Pauli Exclusion Principle, no two electrons in an atom or molecule can have the same four electronic quantum numbers.

Because an orbital can only hold a maximum of two electrons, the electrons must have opposing spins.

Thus, the correct option is A.

I'm 99% sure it is A Ionic

Answer: It’s B, Polar covalent

Explanation:

As the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.

Effective nuclear charge of an atom is the attraction force of positive charge of  protons present inside the nucleus acts as an  valence electrons.

The effective nuclear charge is alway slower  than the total number of protons of the nucleus because of  shielding effect. Where Z is the atomic number and S is the number of shielding electrons.

Therefore, the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.
