I understand the academic integrity policies at laurier and its consequences for violating them. Application Questions: Valence refers to the number of electrons an atom can donate or accept when forming chemical bonds , Equivalent weight on the other hand refers to is a measure of ions that can combine with a fixed weight of a substance in a chemical reaction. So valence is a measure of forming chemical bonds while equivalent weight is how much an ion can replace another in a chemical reaction.
According to the Bohr model of hydrogen atom, the kinetic and potential energies of the electrons vary as .......... .. and... distance of electron from the nucleus. respectively. where r is the The square of the wavefunction, y}, gives us the Absorption of a given amount of energy gives rise to a larger increase in entropy the the initial temperature. Orbital energies in multi-electron atoms are mere difficult to calculate due to the additional Select the correct answers from the following multiple choice questions.
All matter is made of particles called atoms. An atom is smallest unit of matter. A matter can be solid, liquid or gas. When a group of atoms bond together this makes a molecule. The molecule is the base of chemical compounds that is involved in chemical reactions.
Matter is made up of atoms; atoms are made of positively charged protons, neutral neutrons, and negatively charged electrons. 3. The measure of space that the molecules occupy (volume) is derived from the space in between the molecules and not the space the molecules contain themselves. 4. The motions for: • Solid- are not able to move out of their positions relative to one another, but do have small vibrational movements.
Hana Phan Mrs Thomas Honors Chemistry P. 2 9-20-17 Chapter 2 Booknotes 2.1 What is matter? matter - anything that has mass or volume volume - the amount of space an object occupies mass - a measure of how difficult it is to change the object’s state of motion atoms - the basic unit of matter molecules - a neutral group of atoms held together by chemical bonds physical properties - properties that can be observed or measured without changing the composition of matter state - the condition of being a gas, liquid, solid, plasma, or neutron star chemical properties - properties that can be observed only when substances interact with one another Matter is anything that has mass or volume. Volume is the amount of space an object occupies while
A nucleus of an atom is accompanied by several electron shells that orbits around it. Each shell is only allowed a certain number of electrons. The first layer can hold 2, the second layer can hold 8, and the third layer can hold 18 electrons. All atoms prefer a full outer shell, however only noble gases hold them. This causes atoms to either give up or gain electrons from other atoms they encounter to have a full outer shell.
Atoms are the basic building blocks of all matter(Doc.3). These small particles have a nucleus and a certain number of protons ,neutrons ,and electrons(O.I). The number of protons is independent to the element, and can be used to find it on the periodic table(Doc.2). Protons are positively charged particles(Doc.3).
The electromagnetic force causes repulsion between the like-charged protons (positively charged). Both the electromagnetic force and the nuclear force act as opposites which can result in an nucleus being highly stable or highly unstable. This result is affected by which force is dominant in the nucleus, the more dominant the nuclear force it the smaller the nuclei and more stable the
Like charges repel each other, whereas, unlike charges attract each other due to the presence of an electric field. Annotated Timeline 1600- William Gilbert can be correctly called the father of electricity as he “first coined the term "electricity" from the Greek word for amber. Gilbert wrote about the electrification
Ohm’s law is considered to be the basic electrical engineering law that all other electrical engineering laws use in their applications. Its practical applications extend from small circuits to cell phone batteries to rockets. In addition to Ohm’s law, Coulomb 's law is also widely used in both physics and chemistry. In physics, it is considered to be one of the basic laws, while in chemistry it can be used to calculate the force between the protons and electrons of atoms. Another application of this law is the study of crystal structures, as the ions of the crystals arrange themselves so that the electrical forces are balanced.
However, to quantify information means not only involving numbers or
Particles are labeled in many ways. One way particles are referred to be as atoms (elements). They’re identified by their properties, number or protons and neutrons and atomic number. Another way particles are referred are as molecules (covalently bonded- nonmetal to nonmetal). For example, water is a molecule because it’s composed of nonmetals.
The quantum numbers are basically different orbitals that electrons can be found on. The different orbitals are s,p,d, and f. Each level can only hold a certain amount of of electrons until they move on to the next. The s orbital can hold 2 e-, the p orbital can hold 6 e-, the d orbital can hold 10 e-, and the f orbital can hold 14 e-. A way to find the quantum number of an element is to use the diagonal rule.
One is an electric charge. An electric charge exerts a force. Another is called an electric current, which is the movement of an electric charge through something ("Electricity"). For example, electric fences constantly have an electric current pumping an electric charge through the wire. So, when it is touched, the electric current goes through whatever is touching the wire ("Electricity").
Measurements, Calculations, and Significant Figures Measurements, calculations, and significant figures are vital mathematical terms used to understand the basic concepts of physics. Knowing how to properly make measurements and apply the necessary calculations to obtain accurate answers will surely prove beneficial in physics, but having that knowledge will also help you throughout your entire life. Therefore, it is important to understand the processes and numbers involved when using measurements, calculations, and significant figures. Measurements are used to identify the specific characteristics of an object, such as length, size, and amount. One must use the proper measuring device, depending on the conditions of the experiment and
