A biochemist who is studying the properties of certain sulfur (s)-containing compounds in the body, wonders whether trace amount
Leni [432]

Elements of the same group show similar chemical properties as they have the same number of valence electrons. Sulfur belongs to the group 16 or 6 A or the oxygen family with 6 valence electrons. The elements of group 6 A are Oxygen, Sulfur, Selenium, Tellurium and Polonium. All of these elements show similar chemical properties. Therefore, when a biochemist studying the properties a sulfur containing biochemical compounds in the body wants to look at any other non-metal with similar properties, he has to consider other elements of the group 6 A like Oxygen (O), Selenium (Se), Tellurium (Te) and Polonium (Po).

The brightness of a star is most dependent on the star's...Explain why.
gulaghasi [49]
I would say the answer is A - a stars mass

The majority of stars in the galaxy, including our Sun, Sirius and Alpha Centauri A and B are all main sequence stars.


Mass is the key factor in determining the lifespan of a main sequence star, its size and its luminosity ( brightness)




Two characteristics define brightness: luminosity and magnitude. Luminosity is the amount of light that a star radiates. The size of the star and its surface temperature determine its luminosity. Apparent magnitude of a star is its perceived brightness, factoring in size and distance, while absolute magnitude is its true brightness irrespective of its distance from earth.
