Q1 b name the three tiny particles which make up atoms ? a write the charge alongside each one ?

Protons

Neutrons

Electrons.

Protons + charge(positively charged)

Neurons no charge.

Electrons - ( negatively charged).

Explanation:

Atom is the smallest unit of a matter that constitutes chemical elements.

It is composed of three particles which are protons,neutrons and electrons.

Protons is positively charged,neuron has no charge and electrons is negatively charged.

Proton and neuron are found in the nucleus while electron is found outside the neuron.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
