The answer to this is CsN
Answer:
Explanation:
Ions:
When an atom lose or gain electron ions are formed.
There are two types of ions anion and cation.
Anion:
When an atom gain electron negative charge is created and anion is formed.
X + e⁻ → X⁻
Cation:
When an atom lose electron positive charge is created and cation is formed.
X → X⁺ + e⁻
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
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
He constructed the glass tube and create vacuum in it. He applied electric current between electrodes. He noticed that a ray of particles coming from cathode to wards positively charged anode. This ray was cathode ray.
Properties of cathode ray:
The ray is travel in straight line.
The cathode ray is independent of composition of cathode.
When electric field is applied cathode ray is deflected towards the positively charged plate.
Hence it was consist of negatively charged particles.
Neutron and proton:
While neutron and proton are present inside the nucleus. 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+
Symbol of neutron= n0
Mass of proton=1.672623×10-27 Kg
Mass of neutron=1.674929×10-27 Kg

Answer: When a combination reaction occurs between a metal and a non-metal the product is an ionic solid.
Explanation: Another hint(s): When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide. This specific combination reaction produces the bright flame generated by flares.
Answer:
0.893mol
Explanation:
n = m ÷ M
= 275 ÷ (23 + 80)
= 2.67 mol
* now use the Mol ratio *
NaBr : FeBr3
6 : 2
2.67 : x
5.67 = 6x
n( FeBr3 ) = 0.893 mol
