a lower melting point and a lower boiling point since the effective nuclear charge decreases going down a group therefore the amount of force needed to repel the electrons from the protons is weaker.

What is the total number of elements in the ''properties of six elements at standard pressure'' table that are solids at stp?
Standard temperature is 0 degrees Celsius so you are looking for the elements that have a melting point above 0 degrees Celsius. The answer is 4 elements. Elements E, G, L, and Q.
What is the total number of elements in Group 17 that are gases at room temperature at standard pressure?
There are two that are gases, fluorine and chlorine.
What are the three elements that exist as a gas at room temperature and pressure?
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
Why is natural gas considered a gas?
Because at standard temperature an pressure it meets all the criteria expected of a gas.
Which of the fallowing can undergo sublimation carbon or sodium or oxygen or iodine?
Among the four elements listed in the question, only iodine can undergo sublimation at standard pressure.
Can a element be in a form of a solid?
I'm pretty sure all elements have a freezing temperature at standard pressure.
What is the Standard pressure of a substance to become a gas?
Standard pressure is defined as 1atm, or 760mmHg. This is sea-level atmospheric pressure here on earth.
What is the total number of elements in period 2 that are gases at room temperature and standard pressure?
4

What does bromine and mercury have in common?
They are the only two elements that exist in the liquid state at standard temperature and pressure.
What is the total number of elements in group 17 that are gases at room temperature and standard pressure?
its either123or 4
Give me 20 examples of liquid elements?
At standard temperature and pressure, there aren't 20 liquid elements. The only one would be mercury and bromine. If you change the temperature and pressure appropriately, any of the elements could conceivable be a liquid.
How are elements indentified on the periodic table?
Elements in the table are identified by different things. What they are made of, atomic mass, and atomic number. Elements can also be identified by what state of matter they are at zero degrees Celsius and standard pressure which 1atm. The most current, standard table has 117 different elements.
Does the sea have more air pressure than the mountain?
The higher the elevation the lower the air pressure. Sea level is considered the standard for air pressure measurement.
What is the total number of elements in Group 17 that are gases at room temperature at standard pressure?
There are two that are gases, fluorine and chlorine.
How many ml in 6000 cm?
Of water? 6000 ml at standard pressure. For other compounds and elements, it depends on density.
What are the three elements that exist as a gas at room temperature and pressure?
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
