Answer:
Nucleus contain protons and neutrons while outer part contain electrons.
Explanation:
Atoms are the fundamental unit of matter. Every thing in the universe that occupy space and have mass is called matter. we can say that every matter is composed of atoms. while the atom is composed of subatomic particles called electron proton and neutron.
Subatomic particles Relative charge Relative mass
Proton +1 1
Neutron 0 1
Electron -1 0.0005
Electron:
The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.
Symbol = e⁻
Mass= 9.10938356×10⁻³¹ Kg
electrical charge on electron= -1.6022 × 10⁻¹⁹ C
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
Proton and Neutron:
An atom consist of positively charged central core (nucleus) that is made up of Proton and neutron. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.
Symbol of proton= P⁺
electrical charge on proton= +1.6022 × 10⁻¹⁹ C
Mass of proton=1.672623×10⁻²⁷ Kg
Symbol of neutron= n⁰
Mass of neutron=1.674929×10⁻²⁷ Kg
electrical charge on neutron= 0

Answer: Prince Shotoku's Constitution
Explanation:
Japanese schools were modeled after the Seventeen Article Constitution also known as Prince Shotoku's Constitution as he was the progenitor of the text.
The document which was based on the Confucian and Buddhist values, was issued in 604 CE when Prince Shotoku was regent and was meant to give support to the notion of a centralized state where people were ruled by one person.
It also called for officials of the nation to be elected not because of their family name but based on their ability to do the required work amongst other things.
Answer:
TVEL is developing mixed-oxide (MOX) fuel and REMIX fuel, with both using recycled uranium together with plutonium. This is the dual-component approach. "We're very actively engaged in this and right now it is cost-intensive,"
