**don't worry more questions to come :)

Answer 1

1. The number of which atomic particle determines the identity of an element? (3 choices)

proton


2. Which of the following has almost no mass? (3 choices)

electron

3. Which of the following orbits the nucleus? (3 choices)

electron

4. Metals are: (3 choices)

malleable [they are typically so].

5.The principal quantum number indicates the: (3 choices)

main energy level.


6. The outer energy level of a noble gas is: (3 choices)

filled.


7. The modern periodic law states that properties of elements are functions of their: (3 choices)

atomic numbers

Answer 2

1 The number of protons the nucleus has determines the identity of the element.

2. the elctron has mass but it is tiny (1/1831 of a proton)

3. electron moves on the outside of the tiny nucleus.

4.Metals are malleable (can be beaten into sheets) , conduct electricity and are good conductors of heat and are ductile ( can be pulled into wires

5. main energy level N L = the number of sub levels and m = the number of orbital in each sub level.

n can have values of 1,2,3 --- l can have valures of 1,2,,up to n-1)

and m can have value of 0, +1 r-1 ,2,-2 up to + or -l

6 atomic number. It is the atomic number that determines the number of electrons an atom of an element can have and be neutral
