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.

Period of a simple pendulum = 2π √(L/G)
(25 sec/15) = 2π √(L / 9.8 m/s²)
5/3 sec = 2π √(L/9.8 m/s²)
5 sec / 6π = √ (L/9.8 m/s²)
(5sec · √9.8m/s²) / 6π = √L
Square each side:
(25 s²) · (9.8 m/s²) / 36π² = L
L = (25 · 9.8) / (36 π²) meters
L = 0.69 meter
Answer:ring closure result in fewer molecules
Explanation:
entropy is a measure of the amount of disorderliness in a system.
Therefore, the connection causes orderliness in the ring closure
Answer:
h = 20.36[m]
Explanation:
To solve this problem we must calculate the perimeter (length of a circumference) of the circumference, which is denoted by the following equation:
L = 2*π*r
where:
r = radius = 0.9[m]
π = 3.1416
L = 2*(3.1416)*(0.9)
L = 5.654[m]
Now we know that the pulley or circumference had to rotate 3.6 times to get the water out of the well. In this way the depth of the well can be calculated by means of the following equation:
h = 3.6*L
h = 3.6*5.654
h = 20.36[m]
