1. 1. Identify the elements that have the following electron configurations. Be mindful, some may be in their excited state.
(A) 1s 2s 2p 3s 3p?
(B) 1s? 2s 2p 3s 3p 4a? 3d10 4p4
(C) 1s2s22p% 3p?

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
