For each increase of 1 point on the Richter scale how much more energy is released?
one number up releases 30 times more energy than the lower number,one number down is 30 times less than the higher number.
Why is the number of electrons more than nucleus in the sea of electrons model?
In any neutral object the number of electrons is equal to the number of protons. All metallic elements contain more than one proton in the nucleus. Therefore there will be more electrons than atomic nuclei.
Is 5 yards less than 140 inches?
It is 198 inches, so it is greater.
What Does the number of protons always equal to?
No An atom may have less, the same, or more neutrons than protons. The number of neutrons determine which isotope of an element you have. You do expect the number of protons and electrons to be the same however. If an atom loses or gains an electron to cause the number of electrons and protons to be mismatched we call that an ion rather than an atom.
Why are some isotopes weighted more heavily than others?
The type of element is decided by the number of protons in it's nucleus. Number of neutrons are either equal or more than number of protons. Mass of proton and neutron is almost equal and that of electron is almost negligible as compared to both of others. As number of neutrons differ, mass of the elements also differ. Though they have 'same' chemical properties. Such atoms with different mass are called Isotopes. If the number of neutron is more, then such Isotopes are having more mass (or weight.)
What is twice a number is equal to five more than four times the number?

Solve the equation for two less than four times the number is equal to two more than three times the same number?
4/7
If a number is greater than 1 would three times that number be less than equal to or greater than3?
If a number is more than 1, then three of it must be more than 3.(If I give you more than a dollar three times, you certainly wind up with more than $3.)

What is two more than three times a number is at most 37?
3x + 2 is less than or equal to 37
What is algebraic expression for twice a number is equal to eight more than four times the number?
2 x = 8 + 4x
How do you write the equation of 3 more than 8 times a number is equal to 19?
19=(8xn)+3
How do you write three times a number is equal to 8 more than twice the number?
It is: 3x = 2x+8 and the value of x is 8
