By what property did Moseley suggest that the periodic tabe be arranged?
After atomic numbers Henry Moseley supported the arrangement of periodic table of Mendeleev after atomic numbers and properties by a strong physical conception: study of the lines of X-ray spectra of chemical elements. It is a true relation between atomic numbers of elements and the wavelenghts of the characteristic X-ray lines.
What is cominitive property?
The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.
Mineral hardness scale name?
It is the Mohs scale of mineral hardness. It characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. The scale assigns numbers 1-10. 10 being the hardest of minerals(e.g. diamonds), and 1 being the softest minerals(e.g. talc). Generally minerals with a H<5 are softer minerals and minerals H>5 are harder.
What scale is used to rank the hardness or softness of minerals?
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
Are elements organized by atomic weight and physical properties?
Elements are scientificaly organised according to their Proton numbers. Those with smaller proton numbers come first.
Which property of minerals is expressed in numbers?
hardness
What physical properties of minerals can be expressed in numbers?
Density, boiling point, melting point, concentration etc...
Which properties of minerals can be expressed in numbers?
The crystallographic axes of minerals are expressed as numbers. As such these numbers can also be used to describe the orientation of mineral cleavage planes. The Mohs hardness, specific gravity, and melting point of minerals are also properties that can be expressed numerically.
What properties of minerals is expressed in numbers?
hardness
Which physical properties can be expressed in numbers?
hardness
What 2 properties of minerals can be expressed in numbers?
Two properties of minerals that can be expressed in numbers are hardness and specific gravity. Hardness is usually determined using the Mohs scale and is expressed as a number between 1 (softest) and 10 (hardest). Specific gravity is the ratio of a mineral's density compared to the density of water and is expressed as a number.
Quantity?
Any physical property that can be measured and represented in numbers.
Every irrational number can be expressed as a quotient of integers?
The statement is false; in fact, no irrational number can be exactly expressed as a quotient of integers because this property is the definition of rational numbers.
Is numbers of protons chemical or a physical change?
The number of protons in a nucleus is a property of the atom, not a change.
The numbers that are expressed using exponents?
All numbers can be expressed using exponents.
How is rational numbers different from irrational numbers?
Rational numbers can be expressed as fractions whereas irrational numbers can not be expressed as fractions.
What is rerational and irrational numbers?
Rational numbers can be expressed as fractions whereas irrational numbers can not be expressed as fractions
