Which family does it belong to?
How many protons, neutrons, and electrons does its neutral atom have?



Please help with the non-answered ones, following sodium please ^^

Answers

Answer:

11

Explanation:

An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 - 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons

Answer:

Sodium: Na

It is a metal

It's family is Alkali metals

Hey guys, so earlier today i ask ya'll how to get my crush to notice me and mostly everyone said to like be her friend and like ask her to hang out and to shoot my shot. So now my question is "should i still tell her i like her if she's my best friend?"

Answers

Yess you just got to risk it cuz if you don’t then you’ll regret it after wards and it’s going to eat you after wards so just tell her and give her time and If it goes wrong then ask her if y’all could still be friends
Yes, if you don’t ask now you may never know if she likes you or not.
A few years ago I had a crush on this person who I now think liked me back. Me and this person were friends but never told each other. We are still kind of friends but no where near as close. Maybe if one of would have said something back then we would not be where we are today. So if you don’t tell them now you might just end up drifting apart

What are energy levels

Answers

Answer:

set distances were electrons can be sensed.

Explanation:

Energy levels are set distances from the nucleus of the atom where electrons can be sensed. Electrons are small, negatively charged particles in the atom that pass through the positive nucleus in the center. The energy levels are a little like the steps of the stairs. You may stand on one step or the other, but not between the moves. The same thing goes with electrons.

Which of the following problems would be a direct result of humans building along the ocean shore zone?


A. the erosion of the sand and soil from the shoreline


B. sand dunes and vegetation being disturbed


C. the movement of sand from one place to another


D. sand being washed away over long periods

Answers

Answer:

I think it is B.

Explanation:

The erosion of the sand and soil from the shoreline would be a direct result of humans building along the ocean shore zone. When humans build structures along the shoreline. This can lead to increased erosion of the shoreline and loss of the beach.

Building along the ocean shore zone can have several impacts on the natural environment. One of the direct impacts is the erosion of the sand and soil from the shoreline. This occurs because construction can disrupt the natural processes that maintain the beach, such as the movement of sand and the protection provided by vegetation.

For example, building seawalls or other structures can prevent the natural movement of sand and sediment along the beach. This can lead to erosion of the shoreline, as the sand is no longer able to accumulate in areas where it is needed to protect the shoreline. These plants help to hold the sand in place and protect the beach from erosion.

Water evaporating in an open system, water freezing, cookie dough baked into a cookie, and sugar dissolving into water are all examples of statements that demonstrate the law of conservation of matter.

What is law of conservation?A conservation law in physics asserts that a specific observable property of an isolated physical system doesn't change over time.A physical property, or measurable amount, does not change over time in an isolated physical system, according to the conservation law, often known as the law of conservation, which is a principle in physics.According to the principle of mass conservation, neither chemical processes nor physical changes can create or destroy mass in an isolated system. The mass of the products and reactants of a chemical reaction must be equal, in accordance with the law of conservation of mass.

Which statement describes an attribute of an artesian well?
O requires a bucket
O uses natural pressure
O needs a mechanical pump
O is heated by hot rocks or magma
Please only give a ONE answer.

i said/asked calmly​

Answers

An artesian well is describes as having pressure. Some with high pressure.

The statement that describes an attribute of an artesian well is B. Uses natural pressure.

Artesian wells rely on natural pressure by accessing an underground water source that is enclosed between layers of impermeable rock or clay. The water within the aquifer is naturally pressurized due to the weight of the overlying rock or the slope of the land.

When a well is drilled into the aquifer, this existing pressure allows the water to rise to the surface without the need for a mechanical pump.

This utilization of natural pressure distinguishes artesian wells from other types of wells, as they do not require artificial pumping mechanisms to extract water.
