Answer:Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.
The Higgs Boson is the only known particle that gives mass to other particles/atoms. Particle physicists and theoretical physicists are arguing that there are more than one type of Higgs Boson.
Answer:
2.52kg
Explanation:
80mm = 8 cm
0.15m = 15 cm
volume of the container = 10m × 8cm × 15cm
= 1200 cubic centimetres
mass = density × volume
= 2.1 × 1200
= 2520g
2520/ 1000
= 2.52kilograms
Explanation:
When atoms forms ion, they either lose or gain electrons.
In an atom, we have three subatomic particles;
- Protons are the positively charged particles
- Electrons are the negatively charged particles
- Neutrons carry no charges.
A neutral atom has equal number of protons and electrons.
A positively charged atom has more protons than electrons which implies that they have lost electrons.
A negatively charge atom has more electrons than protons suggesting that they have gained more electrons.
If we are given Na, it will for Na⁺ when it loses the electron in its outermost shell. Hence the number of protons is now more and the atoms is positively charged.
