Which of these elements has physical and chemical properties most similar to silicon (Si)?
1. Germanium (Ge) would have the most similar physical and chemical properties to Si. Remember that elements in the same group have similar chemical and physical properties.
1. Which 2 elements have the most similar chemical properties A)Cl:Ar B)Li:Na C)k:Ca D)C:N ? 2. Which elemen?
B, because the two elements are in the same group of the periodic table, so they have the same number of valence electrons and thus similar chemical properties
Only atoms of the same element can have the same chemical properties with different physical properties. Such atoms are called ISOTOPES and their existence is known as ISOTOPY. examples are carbon-12 and carbon-14, chlorine -35 and chlorine- 37. Hydrogen has three isotopes i.e protium, deuterium and tritium. They have the same chemical properties because they have the same number of protons and electrons. Their physical properties are different because of the difference in the number of neutrons in their nucleic.Allotropes, will also have the same chemical properties but may differ in their physical appearance ( properties). examples are Rhombic sulphur and monoclinic sulphur, White phosphorus and red phosphorus, Diamond and graphite.You cannot have different elements with the same chemical properties and different physical properties. Rather atoms of the same element having the same chemical properties and different physical properties.You could have elements that are diagonally related to each other and show similarities in properties (chemical and physical) in the periodic table. Such as Lithium and Magnesium, Beryllium and Aluminium, Boron and Silicon
The first thing you learn about chemical properties should be to understand the periodic table. The columns are the family groups, putting similar elements together was the starting point of discovering the table in the first place.Similar chemical properties are represented by going down any column in the periodic table, these are also called groups, because they have similar properties. We later learned they have similar valence shell structures.Even then there are distinct trends downward due to the core. The lower ones in a group tend to me more similar due to saturation of shielding effects and shrinkage to counterbalance larger size.Since the Noble Gases are least chemically active anyhow, I would choose perhaps something like xenon and kyypton, although krypton is even less reactive.
What are two elements that have properties similar to those of the element sodium?
"the actual and chemical residences of aspects are periodic applications of their atomic numbers." this is maximum serious to undergo in recommendations that till now than our "modern-day" periodic regulation, the Periodic table of things was once arranged in accordance to increasing atomic weights, and not by skill of utilising atomic form. English chemist John Newlands and Russian chemist, Dmitri Mendeleev ("father of the Periodic table"), each and each categorised the climate on the muse of increasing atomic weights. The present regulation (and equipment of team) was once utilized first by utilising Henry Moseley in 1914.
The elements in the same group have the same physical and chemical properties because their number of electrons in their valence shell remains same.
The basic building blocks are the same but the arrangement differs, in a very orderly manner according to quantum mechanical rules but different. Therefore each element, molecule, composite structure has its individual set of properties. Lets start small a one proton atom hydrogen has one electron when neutral, however, its orbital structure allows 2 electrons to be attracted to the nucleus so H is reactive and exists normally as H2 and H can also bond to many other different atoms. The Helium nucleus has 2 protons so the neutral molecule has 2 electrons in a filled orbital and has little tendency to lose, share or gain electrons so the He atom exists as a single atom, unreactive, molecule. As the nucleus increases in the number of protons[and neutrons another story] The number of energy levels and their complexity increases and the different kinds of reactivity multiply, Time to start reading the chemistry books.A simple analogy bricks make a building how they are arranged tells what kind. People and even other mammals and other life have essentially the same molecular buildup Yet we differ, different amounts, some kinds, and arrangement of molecules.
Do planets all share a few common chemical elements?All the planets of our solar system share most common elements from Hydrogen up to Uranium.Generally speaking, the closer to the Sun the more lighter elements have been blown outward by solar radiation and solar wind, so you tend to find a higher portion of heavier elements on the inner planets and more lighter elements in the gas giants.For example, Earth (with high gravity and more solar distance) has been able to hold onto more of its hydrogen (in the form of water) than Mercury. Venus is so hot that much of its hydrogen has escaped to space, but its thick atmosphere keeps absorbing trace amounts from the solar wind. Mars has ice, Jupiter, Saturn, Uranus, and Neptune are mostly hydrogen, with additional helium, carbon, nitrogen, oxygen, and traces of other elements with likely the heaviest elements at their cores.The most common elements in Earth’s crust in order of abundance are:Oxygen, Silicon, Aluminum, Iron, Calcium, Sodium, Potassium, Magnesium, Titanium, Phosphorus, Manganese, Fluorine, Carbon, Sulfur, Barium, Strontium, etcAll or most planets in our solar system contain these elements in at least trace amounts, but the proportions change from heavier to lighter as you move away from the Sun.
The position of an element in the Periodic Table of the Elements is determined by one thing and one thing only: the number of protons in the nucleus of that element.Thus, all isotopes of any given element - say iron (Fd) have exactly the same number of protons in their nuclei. That says they are isotopes of the element iron.As you know, there are also things called neutrons in the nucleus of atoms. The number of protons plus the number of neutrons essentially determines the atomic mass of each isotope. Every element has isotopes with different numbers of neutrons in their nuclei. This means each isotope has an atomic weight that is different from the other isotopes of that element.Now, as for the chemical properties - these are determined by the number of electrons in the outer shells of each isotope’s electron distribution. The chemical reactions of an element have nothing to do with what’s in the nucleus - only the arrangement of the electrons in it’s shells.All isotopes of iron have the same electron arrangement so all isotopes of iron have exactly the same chemical properties.
