Answer: proton number = 16
Electron number =16
Neutron number =16
Explanation: Mass number = 32
Atomic number = 16
atomic number = proton number = 16.
Since the atom is neutral, proton number is the same as electron number i.e Electron number = proton number =16
Mass number = proton + Neutron
32 = 16 + Neutron
Neutron = 32 — 16 = 16
Answer:
Most of an atom consists of empty space. Its mass is concentrated in its center, which is called the nucleus. The nucleus consists of protons and neutrons.
Explanation:
Answer:
q = - 2067.2 J of Heat is giving out when 85.0g of lead cools from 200.0 c to 10.0 c.
Explanation:
The Specific Heat capacity of Lead is 0.128 
This means, increase in temperature of 1 gm of lead by
will require 0.128 J of heat.
Formula Used :

q = amount of heat added / removed
m = mass of substance in grams = 85.0 g
c = specific heat of the substance = 0.128
= Change in temperature
= final temperature - Initial temperature
= 10 - 200
= -
put value in formula
q = - 
On calculation,
q = - 2067.2 J
- sign indicates that the heat is released in the process
The amount of kinetic energu has depens upon an object's speed and its mass.
So its I and IV.
The correct answer is B.
Hope it helps!
