Answer:
The atomic number increases by 1.
Explanation:
The beta minus decay is a process in which a neutron decays into a proton, emitting an electron and an anti-neutrino:
If this process occurs inside an unstable nucleus, we notice that:
- a neutron is converted into a proton, therefore
- the number of neutrons decreases by 1 and the number of protons increases by 1
Keep in mind that the atomic number of a nucleus corresponds to the number of protons it contains: therefore, since this number increases by 1, then the atomic number increases by 1.
Answer:
285 Litre ( 1kg of water occupies 1 Litre )
which is identical to 285 dm^3 ie 285 cubes of length 10 cm
and as there are 10 of these linearly in 1 m then there are 10^3 = 1000 dm^3 in each m^3
giving a volume of 0.285 m^3
Of course if you KNEW that 1m^3 of water has a mass of 1000 kg then you would simply have said that the volume was 285/1000 m^3
Answer:
the atom cannot be divided into smaller particles
electrons orbit around the center of the atom
Atom nucleus surrounded by negatively charged ELECTRONS...
D. 18.1
K^+H^+G^=180° (sum of int angles of triangle)
K^+30+62=180
K^=88°
GH/sinK=KG/sinH
X/sin88=16/sin62
X*sin62/sin62=16*sin88/sin62
X=18.1
