Answer:
Number of proton is 11
Number of neutrons is 12
Number of electrons is 10
Explanation:
For a neutral Na, Sodium atom:
The mass number P+N = 23
Atomic number(E or P) = 11
A charged Na atom that has lost an electron is positively charged and so:
Number of proton = 11 (Still the same)
Number of neutrons = 12
Number of electrons = 11-1=10 (the atom has lost an electron)
If an atom loses electron, it becomes positively charged ie P>E
Answer:
the sum is Rs 4,200
Explanation:
Given that
3 by 7 of the sum is $1,800
We need to find out the sum
So,
Here we assume the sum be x
So the following equation should be made
3 ÷ 7 × x = 1800
3x = 1800 × 7
x = (1800 × 7) ÷ 3
= Rs 4,200
Hence, the sum is Rs 4,200
The same would be considered and relevant
The answer is false..............<span>kinetic theory of gases is a topic that can explain many everyday observations. Have you ever wondered why water boils faster at higher altitudes? Or why inflatable pool toys seem flat after sitting in a cold garage? How about why you can smell a candle all throughout the house? All of these phenomena and many more can be explained by the kinetic theory of gases.</span>
