What else can I help you with?
A substance that is composed entirely of atoms which all have the same number of protons in their nuclei is known as?
two elements having the same number of protons, but differeing in the number of neutrons; thus having slightly different molecular weights are called isotopes of that element...ex. Boron-10(has an atomic mass of 10.012937u) and Boron- 11(has an atomic mass of 11.009305u) Each isotope of Boron has 5 protons, they differed in the number of neutrons which gave each a slightly different atomic mass. note:if two elements have a different number of protons they are no longer the same element or even isotopes of that element..the amount of protons is like a way to identify which atom is which.
Do mass of proton vary for different elements?
The number of protons is different for each element, but the mass of each individual proton is always the same.
Which has more isotopes neon -10 or neon-12?
Neon has the atomic number 10 which means it has 10 protons, it cannot have 12. Different isotopes of an element have the same number of protons but a different number of neutrons. There are three stable isotopes of neon.
How do you find the number of electrons in element?
The Atomic Number of the element is equal to the number of electrons. Also, the number of protons is also equal to the Atomic number; so the number of protons and electrons in any given element is the same!
Isotopes of an element differ in their?
Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. so it should have different mass numbers..
If two objects of the same mass require different amounts of heat to raise their temperatures 10 Kelvin the object have different what?
Specific heat capacities. This is a measure of how much heat energy is required to raise the temperature of a substance by a certain amount. Objects with different specific heat capacities will require different amounts of heat to achieve the same temperature change.
Why do all atoms of an element have the same chemical prperties?
Because they are all the same type of atoms. Oxygen is an element. If you have 10 oxygen atoms, they will all behave like oxygen, since they are the same element.

How many different 10 element subsets can be made from a set of 15 sets?
That is the same as asking 15C10 which is 3003. It is 15! divided by (15-10)!(10!) This is 15x14x13x12x11 divided by 5x4x3x2x1 or divided by 120 or 360360=3003
Is neon lithium?
No. Lithium is an element with atomic number 3 (or 3 protons) and neon is an element with atomic number 10 (or 10 protons). Both are not same.
What is the number of ways to arrange 6 objects from a set of 10 different objects?
10 over 6, which is the same as (10 x 9 x 8 x 7 x 6 x 5) / (1 x 2 x 3 x 4 x 5 x 6).
Do mass of proton vary for different elements?
The number of protons is different for each element, but the mass of each individual proton is always the same.
Does heavier objects fall faster that light ones?
That depends. 10 lbs. of bricks will fall at the same speed as 10 lbs. of feathers. Meanwhile, a cinderblock will fall far faster than a single feather. If two things are the same weight, they will usually fall at the same speed. If two things are different weights, they will fall at different speeds. ^ This only takes effect when wind resistance is NOT added.
If a sodium ion is isoelectronic with neon why is it still considered sodium?
Although a sodium ion and a neon atom may have the same number of electrons, they are not the same element because the number of protons in the nucleus is different. Sodium has 11 protons, giving it an atomic number of 11, while neon has 10 protons and an atomic number of 10. Therefore, even though they may have the same electron configuration, the identity of an element is defined by the number of protons in its nucleus.
What prefix describes a molecule with ten atom of the same element?
It's not a prefix but a subscripted postfix '10'Example: decane C10H22 with 10 atoms of the same element Carbon (and 22 H's)
What is the general atomic number of neon?
The atomic number is the number of protons in an atom. The number of protons in an atom is what gives the atom its elemental identity. The number of neutrons can change resulting in different isotopes of the same element. The number of electrons can change, resulting in different valence states of the same element. If the number of protons changes, then an atom of neon is no longer neon. So the atomic number of neon is always 10, because neon always has 10 protons.
10 kinds of isotopes and their application?
Different atoms of the same element possessing different atomic masses but having same atomic number are known as Isotopes. Since the isotopic atoms have the same atomic number, they must contain an equal number of protons. As their atomic masses are different, there must be a difference in the number of neutrons they possess. They will show similar chemical properties but their physical properties will be different due to different masses.
