1. By accepting electron(s) from a metallic atom to form ionic bond.
2. By sharing electron(s) with non metal to form covalent bond.
Non metal form bonds by:
1. Accept electron(s) from a metallic atom to form ionic bond. Ionic bond is formed when there is a transfer of electron(s) from the metallic atom to the non-metallic atom. This can be seen when sodium react with chlorine to form sodium chloride as shown below:
a. Sodium (Na) lose it's valence electron to form sodium ion (Na+) as shown below:
Na —> Na+ + e-
b. Chlorine (Cl) accept the electron to form the chloride ion (Cl-) as shown below:
Cl + e- —> Cl-
Combining both equation, we have:
Na + Cl + e- —> Na+ + Cl- + e-
Cancel out the electron
Na + Cl —> Na+Cl-
Now we can see that the non metal i.e Cl accept electron from the metal i.e Na to form ionic bond.
2. By sharing electron(s) with a non metal to form covalent bond. Covalent bond is formed when there is a sharing of electron(s) between the two atoms involved. This can be seen when hydrogen atom combine with another hydrogen atom to form hydrogen molecule as shown below:
H + H —> H2
Nonmetals can form different types of bonds depending on their partner atoms. Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. ... Atoms form covalent bonds in order to reach a more stable state.
A block of mass m = 2.0 kg lies on a rough ramp that is inclined at an angle θ = 20oto the horizontal. A force F of magnitude 5.0 N is applied to the block in the horizontal direction (not parallel to the ramp).a) If this force is just large enough to start the block moving down the ramp, what is the coefficient of static friction μsbetween the block and the ramp?b) If the coefficient of kinetic friction between the block and the ramp has a value of 0.40, what is the magnitude of the acceleration of the block along the ramp as this force is applied to the block?c) What is the work done by this applied force if the block travels a distance of 2.0 m down (i.e., parallel to) the ramp?
a) 0.64 b) 2.17m/s^2 c) 8.668joules
The block was on the ramp, the ramp was inclined at 20degree. A force of 5N was acting horizontal to the but not parallel to the ramp,
Frictional force = horizontal component of the weight of the block along the ramp + the applied force since the block was just about move
Frictional force = mgsin20o + 5N = 6.71+5N = 11.71
The force of normal = the vertical component of the weight of the block =mgcos20o = 18.44
Coefficient of static friction = 11.71/18.44= 0.64
Remember that g = acceleration due to gravity (9.81m/s^2) and m = mass (2kg)
b) coefficient of kinetic friction = frictional force/ normal force
Fr = 0.4* mgcos 20o = 7.375N
F due to motion = ma = total force - frictional force
Ma = 11.71 - 7.375 = 4.335
a= 4.335/2(mass of the block) = 2.17m/s^2
C) work done = net force *distance = 4.335*2= 8.67Joules
Which one of the following statements concerning spherical mirrors is correct?A. Only a convex mirror can produce an enlarged image. B. Both concave and convex mirrors can produce an enlarged image.
C. Only a concave mirror can produce an enlarged image, provided the object distance is less than the radius of curvature.
D. Only a concave mirror can produce an enlarged image, provided the object distance is greater than teh radius of hte curvature.
Only a concave mirror can produce an enlarged image, provided the object distance is less than the radius of curvature is correct about spherical mirrors.What are the characteristics of spherical mirrors?
A spherical mirror is a mirror whose reflecting surface is part of a hollow sphere of glass. The spherical mirrors are of two types: concave mirrors and convex mirrors.
A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex or concave. Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices.
Some applications of convex mirror are sunglasses, rear view mirrors, shaving mirror,etc. Some applications of concave mirrors are reflectors, converging of light, solar cooker etc.

What is a real-world application that depends on the relationship between distance, average speed, and time?
One real-world application of the relationship between distance, average speed and time is obviously calculating the mileage of a car. for example, in a given distance, the average speed of a car is this. average speed is distance over time. calculation of the time to reach a distance is another.
Hope this helped!

Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8.6 m/s. The other player has a mass of 90 kg and is running at –9.0 m/s.
93 kg · m/s
For your question:
"Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8.6 m/s. The other player has a mass of 90 kg and is running at –9.0 m/s."
The answer is 93 kg * m/s
A 1.8 kg block of iron at 27 ∘c is rapidly heated by a torch such that 18 kj is transferred to it. what temperature would the block of iron reach assuming the complete transfer of heat and no loss to the surroundings? if the same amount of heat was quickly transferred to a 850 g pellet of copper at 23 ∘c, what temperature would it reach before losing heat to the surroundings?
According to Wien's Law, how many times hotter is an object whose blackbody emission spectrum peaks in the blue, at a wave length of 450 nm, than a object whose spectrum peaks in the red, at 700 nm? Please show me your calculations.
According wien's diplacement law
Let be the temperatures corresponding to respectively.
Thus object with is 1.55 times hotter than object with wavelength
The most reactive metals are located at the of the periodic table.
Metals are the substances which tend to lose their valence electrons in order to attain stability.
For example, metals of group 1 are lithium, sodium, potassium, rubidium and cesium.
And, each of these elements have only 1 valence electron present. So, it is much easier to lose just one electron rather than losing 2 or 3 valence electrons.
Hence, alkali metals are the most reactive substances of the periodic table and they are present at extreme left side of periodic table.
Therefore, we can conclude that the most reactive metals are located at the extreme left of the periodic table.
the elements towards the bottom left corner
A car Rounds a curve while maintaining a constant speed. Is there a net force on the car as it rounds the curve? A: it depends on the sharpness of the curve and speed of the car.
B: no - it's speed is constant
How does the quantum mechanical model of the atom describe electrons
The quantum mechanical model describes the allowed energies an electron can have. It also describes how likely it is to find the electrons in various locations around an atom's nucleus.
