Straight up, atomic number identifies the element. And it is determined solely by the number of protons in the nucleus of that atom. The electron count will match the proton count in a neutral atom. Neutron count, and, therefore, Atomic Mass, can vary because there are different isotopes of a given element around. Just as one example, most hydrogen has a single proton for a nucleus, but some hydrogen has a neutron attached to that proton. In even rarer cases, hydrogen can have two neutrons hanging onto that proton. Here's one element, with one set of chemical characteristics, and three different atomic masses. Best to go with atomic number than atomic mass when considering chemical properties.
it plays a strong part in its reactivity, for example the higher atomic mass of the alkali metals, the more reactive they are, the higher the atomic mass of the halogens the lessreactive they are - it all depends if they lose or gain an electron when they react and how far the electron is from the nucleus because it has a force of attraction
The Atomic number is very closely related to the chemical behavior. The Atomic number is numerically equal to the number of protons which in turn determines the number of electrons. For any chemical reaction to occur, bonding of some sort has to take place and that takes place between electrons.
valence
The atomic number is the same as the number of protons. It is unrelated to the number of neutrons.
AMU stands for atomic mass unit. 1 amu is 1.66053892 times 10 up to the negative 27 kilograms.
chemical's and light
Each bond has a bonding energy which is released in a chemical reaction.
Yes
These values are similar.
Dalton's Atomic Theory
The atomic number is equal to the number of protons.
The atomic number is the same as the number of protons. It is unrelated to the number of neutrons.
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
These values are similar.
Most physical and chemical characteristics of a substance relate to the nuclei's neutron-proton composition. The number of protons in a nucleus is the atomic number (Z) and establishes the chemical identity of the atom. Each atomic number corresponds to a different chemical element; there are now approximately 106 known chemical elements that correspond to nuclei containing from 1 to 106 protons.
No, the atomic number relates to the number of protons and electrons. say if the atomic number is 8 and the atomic mass is 17. by looking at the atomic number you can tell there are 8 protons and 8 electrons. but now you want to find the number of neutrons. you see that the atomic mass is 17. so you subtract the atomic number from the atomic mass. which is 17-8= 9. so there are 8protons, 8electrons, and 9 neutrons. hope this helps you.
Mass of isotopes are not integers.
Well, it really depends what you are talking about. For example the word property (a characteristic of matter) can relate to characters in a story. There are two kinds of property physical and chemical. The physical can relate to the appearance of the character, and chemical can relate to how the character reacts with other characters. If you don't know the definitions physical is when the substance can be observed or measured without chemically changing said substance. Some examples are color, luster, malleability, brittleness, odor, taste, density etc. Chemical is the chemical properties of a substance determine whether or not it will react chemically. The chemical activity of a substance is defined as how easily the substance react with another substance.Hope that helps. Now, I couldn't be general, cause this is kind of a broad question! :)
