What does it mean when a star has a high percentage of heavier elements?

when the percentage of heaver elements is high density will be very high! for example you consider the planet mars it is heavier than earth why because the main element present in mars is helium this leads to greater mass ! we know the stars too have life i,e it undergoes many changes before becoming black hole!
In the presence of heavier elements leads to heavier reactions inside the star and may leads to sudden explosions causing nova and super nova and due to these explosions outer parts of the star will explode and these objects will rotate around the universe as a dust ! and these will fall on earth as a meteors,aestroids and comets and finally i can say due to the presence of heavier elements it leads to causing distruction or minimisation of star

How are most of the elements with nuclei heavier than those of hydrogen and helium formed?
Well, Helium is an element, and "substance" can mean a combination of elements and compounds... which are formed according to their chemical properties. Assuming you were asking about pure elements, rather than substances, all elements up to Iron-56 are formed by nuclear fusion, presumably inside of stars. This is due to to Iron-56 being the most stable nucleus in the periodic table. Hydrogen-1 forms Helium-4, Helium combines to form Beryllium-8, Carbon-12, and Oxygen-16. And so on.... up to Iron-56. Fusion of heavier compounds will not result in excess energy (e.g. a star's heat and light) so those nuclear reactions will not sustain a star. Therefore, all elements heavier then Iron-56 are formed by the extraordinary conditions of a super nova. Because earth has abundant elements heavier than Iron-56, it is thought that the matter in our Solar System has been through several solar cycles... In other words, "we are all made of stars".
True or false-most paper does not reflect light very well because its sureface is somewhat rough?
Well, yes, if by "reflect very well" you mean "reflect like a mirror". White paper can have a fairly high albedo, though - referring to the percentage of light reflected.
Which tides are higher then normal during a high tide low or high tides and why?
do you mean spring tide
What does 'shoot for the stars' mean?
to set high goals for yourself
What do you mean by walk in stardust?
It means that your confidence is so high (or you're so high on yourself) that you feel as if you can touch the stars.
When arranged by a atomic masses elements fall into groups with other elements with?
If what is meant is by mean atomic mass , then they almost fall into "groups" or families of elements with similar chemical properties. HOWEVER there are exceptions where the sequence is "odd" notablyArgon is heavier than potassiumTellurium is heavier than iodineThorium is heavier than ProtactiniumPutting potassium with the noble gases and argon in the alkali metals would be confusing.This is why the periodic table is sequenced by ATOMIC NUMBER not by mean atomic mass.
What does endomesomorph mean?
An endomesomorph is someone who is muscular but has a high body fat percentage.

What does paternal uncertainty mean?
if youre referring to a paternity test it would mean the results do not show a high enough percentage to tell who the father is
What does the name Brianne mean?
Brianne is the feminine form of Brian, which is related to the Celtic elements of "hill" and "high, noble."
Which element has a positive charge and is relatively heavy in weight compared to an electron?
elements only have a charge when they are ionised and all ionised elements are much heavier than an electron I think you mean which sub-atomic particle has a positive charge and is relatively heavy compared to an electron This is the proton.
What does high Mono Auto percent mean?
A Mono Auto percentage is based on the percentage of a particular virus in the blood. The Mono Auto test scans for lupus and mononucleosis among others.
What element is heavier than Au?
Note that a higher atomic mass does not necessarily imply a higher density (it does tend to work that way, but there are lots of counterexamples, and for example both osmium and iridium are considerably denser than the much heavier... in terms of atomic mass... uranium). So depending on what you mean by "heavy", the answer might be slightly different.
What is the process called when atoms join together?
If you mean covalent bonding...well then they bonded.
What do the numbers mean in fertilizer?
The numbers of the fertiliser formula show the percentage of Nitrogen (N). Phosphorus (P) and Potash (K). There may also be a list of trace elements.
Why there are many neutrons than protons in metal atom?
I assume you mean "more neutrons than protons". It really depends what metal you are talking about. The lightest metal is lithium; it has 3 protons. One of its naturally occurring isotopes has 3 neutrons, another has 4 neutrons. In the case of heavier elements, the ratio of neutrons to protons increases; this is not directly related with the elements being "metals", just with the fact that they are heavier elements. The general idea here is that for heavier elements, the repulsive forces between protons become larger; more neutrons are then needed to provide stability, since protons and neutrons attract one another using the strong force, but don't have an electrostatic repulsion.
What does moderate to high cellularity mean?
Cellularity is how much of the bone marrow is creating blood vs how much of the bone marrow is not. So, if you have moderate to high cellularity, it would mean that a large percentage of your bone marrow is making blood. If it's low, it would be a lesser percentage. You can find out from your doctor what the percentage of cellularity is. Also be sure to find out what is average for your age. The younger a person is, the higher their cellularity should be.
