To find the number of neutrons.....
NEUTRONS = MASS NUMBER - ATOMIC NUMBER ( PROTONS)
NEUTRONS = 19 - 9
So this element has 10 neutrons
They really have distinctive forecasts now and again. For example, valence bond hypothesis predicts no unpaired electrons in sub-atomic oxygen, while sub-atomic orbital hypothesis predicts two unpaired electrons in the 2 π ∗ orbitals.
The Molecular orbital hypothesis can be checked for this situation since sub-atomic oxygen is paramagnetic. VB hypothesis is sensibly great at giving subjective data about the states of particles, yet MO hypothesis gives more data about vitality levels, bond qualities, and so on.
Answer:
I think another group who didn't receive ice creams
Answer: A. It contains three times as many hydrogen atoms as carbon atoms.
Explanation: Empirical formula is the formula which shows the atoms of the elements in the simplest ratio of atoms whereas molecular formula show the actual number of atoms.
Thus if a compound has an empirical formula of , it means there are thrice number of hydrogen atoms as carbon atoms.
The molecular formula could be written as . Thus if number of carbon atoms are n, the number of hydrogen atoms are 2n.
Answer:
Well they didn't transfer any energy when they weren’t touching and it did t produce any energy if it didn’t move. Since they are on top of each other they are causing momentum on each other creating kinetic energy
Explanation:
