pleas someone help urgent we are writing a test tmr can some one please explain subatomic particles to me...​

n physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles. Particle physics and nuclear physics study these particles and how they interact.

Explanation:

a particle smaller than an atom (e.g., a neutron) or a cluster of such particles (e.g., an alpha particle).

honesty and integrity.

inspire others.

commitment and passion.

good communicator.

decision-making capabilities.

accountability.

delegation and empowerment.

creativity and innovation.

here are the traits of a good leader.i'm not going to give you the examples so you can copy right it.that's illegal but i hope that this you out.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
