Agroup of students working in a high school chemistry lab believe they have discovered a new element! how exciting! upon further testing by scientists (with better equipment), it is found that the new element contains 74 protons and 110 neutrons. 1. what is the atomic number of this element? ¬¬ 2. what is the mass number of this element? 3. is this really a new element? explain your reasoning. 4. give the name and symbol for this 5. when the students discovered it, did they find a solid, a liquid, or a gas? explain your reasoning.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
