Answer:
The sun.
Explanation:
It is closer to Earth, therefore bigger to us, and not just a small point of light.
Answer:
[AR] 4s². EC(Ca)=1s² 2s² 2p⁶ 3s² 3p⁶ 4s²
S=shell
²or⁶ is number of electrons
Explanation:
the number of electrons for the calcium atom is 20 show the first two electrons of calcium will go in the 1s² orbital. the next two electron will go in the 2s orbital and the next 6 electron will go in the 2p orbital.
Answer:
Salt particles will diffuse and towards where it is less that is left !!
so your answer is A !! left through diffusion !!
Explanation:
Answer:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

The mass and volume has direct proportional to each other.
<h3>What is the relationship between mass and volume?</h3>
The volume of the object is directly proportional to its mass which means that if the volume increases the mass of the object increases also increase and vice versa. Due to this direct relationship, the line of regression will go straight between X and Y axis.
So we can conclude that mass and volume has direct proportional to each other.
