Metallic elements can exist on their own as individual atoms.
Nonmetals usually exist as molecules, combining with atoms of themselves.
Nonmetals can exist on their own as individual atoms.
Explanation:
Metallic elements can exist on their own as individual atoms without combining with another atom. They are stable that way. For example gold, copper, and silver.
Non-metals are usually found as molecules in combined states. The molecules are bounded to each other through covalent bonds. Examples are oxygen gas, nitrogen gas e.t.c. When the two atoms combine, they share their electrons to for homonuclear molecules.
Non-metals like the noble gases exists on their own as individual atoms. They are mono-atomic gases and are stable in nature.

Answer:
yes
Explanation:
He used the formula R = VI and obtained an
answer of 2
Two methods of transfer of heat are involved in this process: conduction and convection.
In fact, the metal spoon is heated by conduction because the molecules of the boiling water collide with the molecules of the spoon, releasing heat to it; and also by convection, because in the pot of boiling water masses of hot water goes upward and they give their heat to the spoon, then these masses become cooler and they go down, replaced by other masses of hot water.
Answer:A- mass charge.
This can also be called current.
Explanation:
This is Kirchhoff’s 2nd law.
Kirchhoff’s junction law states that the sum of current(mass charge) flowing in and out of the junction must be equal to zero. This law emphasizes conservation of charge and energy. Charge is also a form of energy and it can neither be created nor destroyed.
Answer:
1.6675×10^-16N
Explanation:
The force of gravity that the space shuttle experiences is expressed as;
g = GM/r²
G is the gravitational constant
M is the mass = 1.0 x 10^5 kg
r is the altitude = 200km = 200,000m
Substitute into the formula
g = 6.67×10^-11 × 1.0×10^5/(2×10^5)²
g = 6.67×10^-6/4×10^10
g = 1.6675×10^{-6-10}
g = 1.6675×10^-16N
Hence the force of gravity experienced by the shuttle is 1.6675×10^-16N
