What else can I help you with?
Should you use atomic number or atomic mass number for electronic configuration?
Atomic number. This gives the count of protons in the nucleus and therefore the posiitive charge of the nucleus. For an uncharged atom it therefore gives the total number of electrons in all shells
What is the Mass number in beryllium?
The atomic mass is the same as the atomic weight therefore it is 9.01218. Beryllium is a non metal element. Atomic mass of it is 9.01. The atomic mass number, which is distinct from the atomic mass and the atomic weight, is 9.
Can you identify an atom without number of neutrons in it?
Every element has a specific number of protons, which is how an element is identified. That gives its atomic number. The number of neutrons can vary, and therefore is not useful in identifying an element.
What is the valency of an element with atomic number 8?
Carbon has a valency of 2, 4. Which might be useful information if it were either a) correct or b) relevant (the atomic number of carbon is 6). The element with an atomic number of 8 is oxygen, which has a valence of 2 (and a most common oxidation number of -2).
Why could you use clues about atomic mass to place elements even though the table is now based on atomic number?
the bigger the mass of an element, the higher its atomic number.
Why is the periodic table useful for studying the properties of different elements?
well, the periodic table is very useful because you have the atomic number, atomic mass, and even the trends across a period or down a group.
What is silicons atomic number?
Silicone is a none metal element. atomic number of it is 14.
What is oxygens atomic number?
Oxygen is in p block. it is a useful gas. oxygens atomic number is 8.
When is a microscope useful for a biologist?
miroscope is a useful tool for biologists because when they do the experiment in so tiny objects it will help to find out the solutions (as we cant see in our naked eyes).Thanks.
Biologists find what useful because this scientific study gives them much information about based on its classification?
Biologists find classification useful because it helps organize and categorize living organisms based on their evolutionary relationships and characteristics. This aids in understanding biodiversity, making predictions about species traits, and guiding conservation efforts.
Titanium atomic number?
The atomic number of titanium is 22. The atomic weight of Ti is 47.88 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
What is the significance of atoms that have the same number of neutrons?
Atoms that have the same number of neutrons are isotopes. Isotopes have the same atomic number but different atomic mass. This is significant because isotopes of an element have similar chemical properties but may have different physical properties, making them useful in various scientific and practical applications.
Should you use atomic number or atomic mass number for electronic configuration?
Atomic number. This gives the count of protons in the nucleus and therefore the posiitive charge of the nucleus. For an uncharged atom it therefore gives the total number of electrons in all shells
How do you find the number protons from the atomic number?
Dear Wiki Questioner, The atomic number of an element is defined to be the number of protons its nucleus! Since the most useful characteristics of an element are the result of the number of protons it has, the scientific community chose to order the elements primarily based off of how many protons they contain. So that means that when we are given an atomic number, we automatically are given the number of protons it contains!
What element is a transistion metal with 30 electrons and is useful to make paint?
The element with Atomic number 30 is "Zn" Zinc.
Find the square root of the atomic number for manganese?
Taking the square root of an atomic number is not particularly useful. Anyway, you can look up the atomic number in a periodic table or some other reference material (searching Wikipedia for "manganese" should work well), and then use a calculator to take the square root.
Why is it more useful to base the periodic table on the number of protons in each atom rather on the atomic mass?
Because all elements have a specific amount of protons, any more or less and they are not the same element. Different isotopes of the same element can largely vary in their atomic mass.
