Answer:
Proton = 119
Electron = 119
Neutron = 183
Explanation:
Mass number (A) = 302
Atomic number (Z) = 119
Proton = atomic number = 119
Since there is no charge on the element, it means the element is neutral.
Therefore,
Electron = proton = 119
Mass number = proton + Neutron
Neutron = Mass number — proton
Neutron = 302 — 119
Neutron = 183
it is important to check the conductivity and pH of pure water to:
1- to check the purity of water and if it healthy or not , and the water source.
2- we have to measure the PH to know the alkalinity or acidity of water. If the PH > 7 so it is acidic , if PH < 7 so it is alkaline.
3- we have to measure the conductivity of the water as it is an indication for the impurity level. and it shouldn't be high to keep the water healthy.
Answer:
Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size. Gas particles are in constant rapid motion in random directions. Collisions between gas particles and between particles and the container walls are elastic collisions.
