When Two Atoms Have The Same Atomic Number They Have The Same Number Of? More specifically, atoms that have the same number of protons in their nucleus belong to the same chemical element. The number of protons an atom has in its nucleus is given by the atomic number. An atom’s mass number tells you
Why Is Water Considered A Compound 2 Points? Water is a compound because it is made up of water molecules. There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion Why is water considered as a compound of two points? Water is a compound
What Were The 5 Most Important Points Postulates In Dalton’s Atomic Theory? The 5 postulates of Dalton’s atomic theory are listed below. All matter is made up of atoms, which are tiny, indivisible particles. … Atoms cannot be created, destroyed, or divided into smaller particles. Compounds are formed when the atoms of different elements combine
What Are The Common Types Of Elements? Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Which type of elements are most elements? Most elements on the periodic table are metals. Visually inspecting the periodic table shows that most elements are metallic. Which type
Are All Atoms Of A Given Element The Same? – Atoms of a given element are identical (meaning they have the same mass and properties). – Atoms retain their identity in all chemical reactions. This is basically the Law of Conservation of matter stating that an equal amount of mass exists before and after a
Why Do 35 17 Ci And 37 17 CI Have The Same Chemical Properties In What Respect Do These Atoms Differ? In isotopes of 17Cl35 and 17Cl37 the atomic numbers are the same; hence, their electronic configuration remains the same, and so are their chemical properties. These differ only in physical contents and weights because
Has An Atomic Number Of 1? Hydrogen is the element that is atomic number 1 on the periodic table. The element number or atomic number is the number of protons present in the atom. Which element has an atomic number of 1? Atomic Number Symbol Name 1 HHydrogen 2 He Helium 3 Li Lithium 4
How Are Atoms Related To Elements Example? A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just
How Do Scientists Think The Elements Are Created? Scientists create heavy elements by bombarding two lighter elements that together add up to the mass of the desired new element. One of the elements is stationary and thus called the target. … A tiny fraction of the time the two elements stick together and form the
Which Is Most Likely True About Electronegativity? Answer: Answer:It is true about electronegativity that it tends to increase across a period. Explanation: Electronegativity is defined as the ability of an element or atom to attract one or more number of electrons towards itself. WHO reported 4 element classification? Explanation : Antoine-Laurent Lavoisier reported four “element”
