Answer: I think so.. (sorry if i am wrong)
Explanation: Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. A physical property is a characteristic of matter that is not associated with a change in its chemical composition.
There is no list, but possibly evaporation.
Answer:
Particles in all states of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. ... Individual particles in liquids and gases have no fixed positions and move chaotically.
Explanation:
Nitrogen and oxygen are the most prevalent in the atmosphere.
Explanation:
calcium ion is denoted as - Ca ²⁺
The number of electrons in a neutral atom of calcium = 20 , but since ,
it is charged atom ,
i.e. +2 , the number of electrons in calcium ion = 18 .
From , the question ,
The mass number = 41 ,
and
since ,
the mass number = number of protons + number of neutrons .
number of neutrons = mass number - number of protons
since ,
The number of protons for calcium ion = 20
number of neutrons = 41 - 20 = 21
Hence ,
number of neutrons = 21.
