How do you decide if a formula repesents a compound or an element?
If the chemical formula contains only one element (such as Mg, K or Cl2) it would be an element. If it contains two or more elements (such as NaCl, CO2 or CuSO4.5H2O) then it would be a compound.
What do you call the letter or group of letters that represents an element?
The letter or group of letters that represents an element is called its chemical symbol. Each element has a unique chemical symbol, typically derived from its name in English, Latin, or another language.

When is each candle lit in the advent wreath?
The first of the four candles - usually, sometimes there's a fifth "Christ candle" - is lit on the first Sunday of advent which can fall on any day between 27th November and 3ird December. On the next Sunday of advent the second candle is lit in addition to the first; so there would be two candles lit on the second Sunday.By the third Sunday the third candle is lit, with of course, the other two candles of the past couple of weeks. The third Sunday of advent is often quite soon before Christmas day itself, when the fourth and last candle is finally lit, amongst the rest.
What does helium do to a lit candle?

What is CuL2 in the periodic table?
CuL2 is not found on the periodic table as a stand-alone element. It likely refers to a compound where Cu represents the element copper and L represents a ligand that is attached to the copper atom. This compound would be a coordination complex, not an individual element on the periodic table.
What particle diagram represents a mixture of an element and a compound?
A particle diagram representing a mixture of an element and a compound would show individual atoms or molecules of the element and compound mixed together without forming any new chemical bonds. The particles of the element and compound would be distinct from each other within the mixture.
What is the symbolic notation of an element having 8 protons 8 electrons and 10 neutrons?
The symbolic notation of this element would be ^18O, where 18 is the sum of the protons and neutrons in the nucleus, O represents the element oxygen.

Why does the priest lit the paschal candle outside of the church on Easter?
During the Good Friday service (and in some traditions the Maundy Thursday service), all the lights are removed from a worship space, with the light of the paschal candle being the last to be removed/extinguished. Because the paschal candle specifically represents Christ's living presence among the people, by extinguishing the candle, we signify Jesus' death. Then, on Easter a fire is lit outside the church and the candle first lit to symbolize Christ's resurrection (usually with a new candle to symbolize new life). That light is then carried into the darkness of the church and from there the light spreads throughout the worshiping community. The symbolism would be ruined if you used a lighter or another candle to light the paschal candle in the worship space because it would no longer serve as the source of all light and life in our midst.
Which of these can vary without changing the identity of an element number?
The mass number can vary without changing the identity of an element, as it represents the number of protons and neutrons in the nucleus. Conversely, changing the number of protons would change the identity of the element, as it defines the element's atomic number.
