What does the atomic symbol?
1. The number of a chemical element in the Periodic Table. 2. The number of protons of this chemical element. 3. The number of electrons (in neutral state) of this element. 4. Also the atomic number is proportional to the atomic weight.
What is the symbol and atomic number for the element iron?
For iron, the symbol is Fe and the atomic number is 26. Iron has an atomic weight of 55.845g/mol
How do you draw a model of the atomic box with atomic number 16 symbol Si and atomic weight 28.0855?
To draw a model of the atom with atomic number 16 and symbol Si, you would have a nucleus at the center with 16 protons and 16 neutrons. Around the nucleus, you would have 16 electrons orbiting in various energy levels, following the rules of electron configuration. The atomic weight of 28.0855 indicates the average weight of the isotopes of silicon.
Elements are represented by what?
Their symbol, atomic weight, and atomic number.
How many neutrons are in antimony 122?
You look up antimony. You discover its symbol is SB. You look on your periodic table. You come to the symbol SB. You see that it is number 51. You know that is also the number of protons in the atom. You know that 122 is the atomic weight. You know that the Atomic Weight mainly comes from the weight of the neutrons and protons. You know that when you have the atomic weight you can subtract the atomic number from the atomic weight and get the number of neutrons.
Is the atomic number and the atomic weight the same?
No, the atomic number is the number of protons and electrons in a given element. The atomic weight is the weighted average of the isotopes in a natural environment.
What kind of element tells atomic number atomic weight and symbol?
An elements symbol is an abbreviation of a chemical element, which makes it easier to read the Periodic Table if you know your abbreviations for each element as it won't be so cluttered. The atomic number is the number of protons found in the nucleus of an atom. In an atom of balanced/neutral charge, the Atomic Number is the number of electrons.
What is the atomic weight of dubnium?
Dubnium, symbol Db, has an atomic number of 105 and an atomic weight/mass of 262.
An atom of the element has an atomic number of 12 and an atomic of weight 24 How many electrons does it have?
It will have 12 electrons.
Atomic number of an element is 6 and atomic weight is 14 it has --- number of protons and --- number of electrons?
The isotope carbon 14: Atomic number = number of protons = number of electrons = 6 Atomic mass: 14,003241
Is atomic number the number of protons and neutrons?
No, the atomic number is the same number of protons and electrons. To find the neutrons, you subtract the atomic weight by the atomic number. Make sure to round the atomic weight as well.
What information does the atomic number of an element give you?
The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D
