How do you write the standard atomic notation for neutral atom?
Beryllium for example would be. 7 2 Be 4 7= The mass number (+Protons and +/- neutrons added) 4 = The +protons 2 = The oxidation state. Beryllium would have 2 valance -electrons, hence the two. It has to lose 2 -electrons to be stable. For a metal it would be how many electrons it has to gain to be stable (Full valence shell). Be = Is obviously the symbol of the element.
What is scientific notoation?
Scientific notation is a way of making really big numbers or really small numbers much easier to work with. It involves taking whatever number you have and multiplying it by some factor of 10. Lets start small- say we want to put the number 23 into scientific notation. We would make it 2.3 x 10^1 . 2.3 x 10 is the same thing as 23. I know, why not just say 23? Well, for a small number like this, we would. Many times in science though, numbers are much too big or small to work with realistically. To write them all out would be a total waste of time, and make things very confusing. So, when we have a number (like Avogadro's constant for example), we simplify it. 602,200,000,000,000,000,000,000 becomes 6.022 x 10^23 Or, take a really small number like .000000000000000035. In scientific notation, we would call this 3.5 x 10^-17.
What are some differences between atomic mass and atomic number?
Atomic mass is how much it weighs, the atomic number is how many protons/electrons it has
10 millimeters equal how many centimeters?
10 centimeters equals 100 millimeters, or in scientific notation 1×102
How many atomic mass has magnesium?
Magnesium is a metal element. Atomic mass of it is 24.
When and why is scientific notation used?
Scientific notation is used in numbers that are very large, or small- also if they include many zeroes. For example, they are used to show atomic values of distances/sizes of celestial beings. (the sun, stars, etc) Or, an electron's weight.
How many 0.8 g in scientific notation?
Scientific notation is a way of representing numbers: it does not have any mass and so there are 0 lots of 0.8g in scientific notation.
How many factors does a scientific notation have?
depends
Why is scientific notation useful in economics?
Scientific notation is useful in economics to compute very large or very small numbers.
How many centimeters in a meter in scientific notation?
1x102cm in a meter
What is the scientific notation for 300000?
The standard scientific notation for 3.00000 is 3*10^0 or 3E0. It can also be written as 300000*10-5 or 300000E-5 (or in many other nonstandard ways).
How many seconds are in 50 years in scientific notation?
1.577836800*109
How many newton in one kilogram in scientific notation?
1 newton
What is the difference of exponent and scientific notation?
scientific notation tells how many times you will move or add zero either left(positive) or right (negative). exponent tells you how many times you will multiply its coefficient.
How do you find the scientific notation of a number?
Ok.... so heres how you find scientific notation: first you have your number then you count how many 0s are after the first digit in the number. then its 10 with the power of however many 0s you counted. Ex. say th number was 600,000,000 the scientific notation would be 8 and 10th power
How is a number expressed in scientific notation?
Scientific notation is when you multiply a number that is between 1 and 10 to 10 to a power. for example: I want to write 3,946,000,000 as a scientific notation. What I do is I divide the number by 10 over and over until the number is 3.946 then how many times I divided 3,946,000,000 by 10 is the exponent of 10 which you multiply by 3.946 and the Scientific notation of 3,946,000,000 is 3.946 * 109.
Scientific notation is a way of making numbers scientific.?
No, it is not. In many branches of science it is necessary to deal with numbers which are very large or very small and scientific notation is used to represent such numbers more easily.
