Which elements have to gain or lose only one electron to become stable?

  1. This is determine by the number of valence electron(which is found by locating the group number the atom resides in) the atom have. Once located, you then recall that all the atoms wants to obtain stability like the Nobel gases (located in group 8 of the periodic table).

Ex. Sodium (Na) has 11 electron.

To gain stability like the gases, Na will gain one more electron to look like the Nobel gas Neon (Ne)

Why are liquid particles arranged the way they are?

Liquid particles are arranged randomly and loosely packed because of their higher kinetic energy compared to solids. While they have some intermolecular forces that keep them close together, they still have enough energy to move around and slide past each other, giving liquids their ability to flow.

How many hydrogen atoms are found in two molecules of hydroxylamine which is 2NH2OH?

There are a total of 8 hydrogen atoms in two molecules of hydroxylamine (2NH2OH). Each hydroxylamine molecule consists of 4 hydrogen atoms.

How much energy must be supplied to break a single aluminum 27 nucleus into separated protons and neutrons if an aluminum 27 atom has a mass of 26.9815386 rm amu?

The mass defect for a single aluminum-27 nucleus is approximately 0.0293 amu (mass of protons and neutrons is less than the mass of the nucleus). To separate the protons and neutrons, you would need to supply energy equal to the mass-energy equivalence of this mass defect, which is approximately 27.3 MeV (million electron volts) using Einstein's famous equation E=mc^2.

Which particles are always made up of more than one atom?

Molecules, compounds, and ions are always made up of more than one atom. These particles consist of two or more atoms bonded together through chemical interactions.

Which two partials of an atom carry electric charge?

Protons carry a positive charge, while electrons carry a negative charge.

What is the relationship between the ionization energy of a mono anion such as Cl and the electron affinity of the neutral atom?

The ionization energy of a monoanion (e.g., Cl^-) is the energy required to remove an electron from the monoanion to form a neutral atom. The electron affinity of the neutral atom (e.g., Cl) is the energy released when an electron is added to form a negative ion (e.g., Cl^-). In general, the ionization energy and electron affinity are related as they both involve the interaction of electrons with atoms, but they are opposite processes in terms of energy change.

What part of atom are responsible for how they interact with other atoms?

The electrons in an atom are responsible for how they interact with other atoms. Electrons are negatively charged particles that determine the chemical behavior of an atom as they are involved in forming chemical bonds with other atoms.

What are neutron stare?

Do you mean neutron stars?

Any atom you can think of has the same number of electrons as protons in the nucleus. Some stars have collapsed under their own gravity so that the electrons have been squeezed into the nucleus. When they do that, they combine with the equal number of protons to form neutrons in every case. So instead of atoms with neutrons, protons and electrons, you are left with just neutrons, and neutrons are much much smaller than atoms. The densities and gravitational fields in the vicinity are enormous.

What is a previously saved configuration?

A previously saved configuration refers to specific settings, preferences, or parameters that have been saved or stored in a system or device for future use. This allows users to quickly revert to a known or preferred configuration without having to manually set each option again.

Two neutrons added to an atom of the element iridium result in?

If it is possible without any other nuclear reactions to be done, it'll give you an isotope of iridium.

What is the charge of a ion that contains 6 protons and 7 electrons?

It is equal to the amount of charge in one coulomb.

and is the amount of charge that passes through a common 100-watt light-bulb in about one second.

What is the charge of a ion that contains 22 protons and 21 electrons?

The charge of an ion is determined by the difference between the number of protons (positive charge) and electrons (negative charge). In this case, the ion would have a charge of +1 since it has 1 more proton than electrons.

What is a calcareous shell?

A calcareous shell is a hard, protective outer covering made primarily of calcium carbonate, found in organisms such as mollusks, corals, and some types of algae. It serves to protect the organism from predators and harsh environmental conditions.

How many neutrons in chlorine 37?

The isotope Chlorine-37 (or denoted as 37Cl) has 20 neutrons per atom. 37 is the mass number (sum of number of neutrons and protons per atom) and we know that the atomic number for Cl irregardless of whichever isotope is 17, which means all Cl atoms have 17 protons. Therefore the number of neutrons for Chlorine-37 is 37 - 17 = 20.

Do minerals carry an electrical charge?

A mineral is defined as a solid inorganic substance of natural occurrence. By this definition, all of the metallic elements are minerals that conduct electricity. Graphite also conducts electricity.

Is CuCO3 an atom?

No, CuCO3, or copper carbonate is a compound made up of an element and a polyatomic ion.

How is the structure of an atom or uranium 235 dfferent to the structure of an atom of uranium 238?

The main difference between uranium-235 and uranium-238 is their atomic masses. Uranium-235 has 235 atomic mass units (AMU) while uranium-238 has 238 AMU. This difference in mass is due to the number of neutrons in the nucleus of each isotope.

Where did you found in an element number of protons and electrons?

The atomic number is equal to the number of protons and electrons, for a neutral atom.

What characterizes the bond formed between two identical atoms?

The bond formed between two identical atoms is known as a nonpolar covalent bond. This type of bond is characterized by the equal sharing of electrons between the two atoms, resulting in a symmetrical distribution of charge. As a result, there is no separation of charge (dipole moment) along the bond axis.

Why are the transition metals so different in chemical character from the s block elements?

They have the ability to form at least one ion with a partially filled 3D orbital, this leads them to be able to switch between states of oxidation and act as catalysts for reaction . In solid form acting as a heterogeneous catalyst they have the ability to donate or accept electron pairs, weakening bonds in reactants lowering activation energy.

e.g. electron configuration of Ni 2+
