What atom of an element with a different number of neutrons?
Isotopes.
When all samples of a material have identical properties and composition it is?
Element
Which is not a characteristic of a compound-?
Different samples of a compound do not have different properties.
Does each element have a unique atomic number?
Yes. The atomic number is the number of protons in the nuclei of an element's atoms, which is unique to each element and determines the element's identity.
What are atoms of the same element that have different neutron numbers called?
Every atom of the same element is also categorized by its number of neutrons. An atom with a certain number of neutrons is an "isotope." Two atoms of the same element (same quantity of protons) can be different isotopes (different quantity of neutrons). Some isotopes are unstable, so most stable isotopes of an element are withing a range of a few numbers. For example, stable isotopes of carbon are Carbon-12 and Carbon-13.
Where was phosphurus discovered?
The Element, Phosphorus (symbol P) was isolated/discovered in Germany by Brandt in 1669.German Alchemists had been experimenting with various urine samples for many years but, Brandt is credited with the 'discovery.'
Process is in control the variations in x-bar and r between different samples of the process output are caused by which assignable causes natural variations sampling bias human error?
If the process is in control, then the variation is termed common cause or what you have stated as natural variation.
What atom of an element with a different number of neutrons?
Isotopes.
When all samples of a material have identical properties and composition it is?
Element
Why do polls have different outcomes?
Because they are based on samples and outcomes vary between different samples.
Why are there variations in atomic mass?
The isotopic composition of natural uranium is not absolutely identical in all ore samples; this is valid also and for other elements. The long geological evolution can influence the isotopic composition.
How many different simple random samples of 7 are possible from a pool of 25?
There are 25C7 different samples of seven from a pool of 25.25C7 = 25!/(7!(25-7)!) = 480 700 different samples of 7
Why is it important to correctly construct the DNA model of the different samples?
Why is it important to correctly construct the DNA model of the different samples?
Which is not a characteristic of a compound-?
Different samples of a compound do not have different properties.
How can someone find free baby samples by mail?
Choose the different brand you wish to use, such as pampers, and go on their website. There they will have a tab where you can order different samples, but you will not be able to order samples of all their products.
Does each element have a unique atomic number?
Yes. The atomic number is the number of protons in the nuclei of an element's atoms, which is unique to each element and determines the element's identity.
What is success independent samples design?
different samples of respondents from the population complete the survey over a time period
