What are examples of elements with one as their valency i.e.give examples of monovalent elements.?
hydrogen silver gold
Are feldspars and hematite examples of native elements?
No. Feldspars and hematite are examples of minerals.
What Sulfur oxygen and phosphorus are examples of .?
Elements
What was an alternate theory used to dispute the theory of plate tectonics?
A proposed explanation for identical species found in divergent locations was the land bridge theory, which supposed shifting dry areas across which living things spread. The further study of rock formations (which were also identical) lent greater weight to the idea that continents were actually joined together in the past.
What are micro and macro elements with examples?
Micro elements are those that are needed in very small amounts by the body. Some examples are: zinc, iodine, manganese, copper, selenium, and iron. Macro elements are those that are needed in larger amounts in the body. Examples are: phosphorus, magnesium, potassium, sodium, and calcium. There is a third group, called toxic elements, that should not be in the body. Examples are aluminum, thallium, mercury, cadmium, and lead.
Are there elements in the theory that are untestable?
Are there elements in the theory that are untestable?
Which scientist proposed that elements consisted of atoms were identical and had the same mass and that compounds were atoms from different elements combined together?
John Dalton first proposed this. Today, it's called Dalton's atomic theory.
What are two ancient greek theories of matter?
Dalton's Atomic theory: all elements contain tiny atoms, that's the only way an element is pure because al atoms of an element were identical and it also explains the identical masses
Which scientists work became the accepted explanation of atomic theory?
Modern Atomic Theory was developed by British scientist, John Dalton. His theory rested on four factors. Chemical elements are composed of atoms. Atoms in an element, are identical to the weight of the element. Atoms of different elements have different weights. To form compounds, atoms are combined in small, whole-number ratios.
What is the column of elements in the periodic table that have similar but not identical properties?
A group of elements.
Who came up with this quote all atoms of a given element are identical but they differ from those of any other element?
Dalton came up with that theory. It was proven wrong, though.
What e are hydrogen carbon oxygen lead and gold all examples of?
They are elements
What are the theories related with transfer of training?
Some theories related to transfer of training include identical elements theory, near transfer theory, far transfer theory, and cognitive theory of transfer. These theories explore how training in one context can impact performance in another context, and how similarities or differences between the training and transfer contexts can affect the transfer of learning.
Can the spectral lines for two different elements be identical?
no, it is impossible
What is a compound of two identical elements known as?
A compound can only consistent of at least two different elements.
What are equal and equivalent sets?
Equal sets contain identical elements. e.g. if A = {1,2,3} and B = {1,2,3}, then A and B are equal - their elements are the same. Equivalent sets have identical numbers of elements. e.g. if A = {1,2,3} and B = {a,b,c}, then A and B are equivalent - they both have three elements.
What is the similarity of Darwin's theory to Darwin's theory?
Darwin's theory is the same as the Darwin's theory. They are identical in every way.Darwin's theory = Darwin's theory I don't understand the question. Please rephrase, I think there is a mistake...
